The resumption of the civil war is just an opening phase of the Sino-American war.
I think 70% of crude oil is used for transportation. Electrification of the transport fleet will remove the need of that.

More like 50%-55%, according to deepseek . And among that,fuel for aviation and heavy equipment cannot be replaced by electricity in foreseeable future

Western sanctions, not international. Western countries made up of only a tiny minority of the world. In time of war, security trumps economy. The Western blockade of China will mean no trade with East Asia. The West will not get any electronics anywhere.

Even if China blocks East/Yellow/South Sea,Japan can still trade with outside via Pacific Ocean,and Korea can go east into Sea of Japan then go into Pacific Ocean

Bio-diesel and other synthetic fuels. Coal-to-oil is also possible.

Check the map. All of Japan is within 2000km of China's North East. Daily bombardment of thousands of Harpy style UAV is totally doable. Korea is even closer.

Not possible as of now
Heard of SAF and CTL?

In 2022, China built capacity of 100k tons per year to produce SAF from gut oil, the first of its kind in the country. The product has already been certified for airworthiness.

中国首套生物航煤工业装置在中国石化镇海炼化首次产出生物航煤,意味着我国生物航煤可实现规模化生产,向大规模生产及商业化应用迈出了坚实的一步。与传统石油基航空煤油相比,生物航煤全生命周期二氧化碳排放最高可减排50%以上,该装置年设计加工能力10万吨,一年基本能消化掉一座千万人口城市回收来的地沟油,每年可减排二氧化碳约8万吨,相当于近5万辆经济型轿车停开一年。

As of 1H 2022, China had already got CTL annual capacity of over 8 million tons. The technology is ready. It was only low crude oil price that had limited the actual utilization and slowed down the push for higher capacity as planned.

截至2022年上半年,煤制油项目共投产8家,总产能823万吨/年,但产量仅为357.2万吨。对照国家能源局印发的《煤炭深加工产业示范“十三五”规划》确定的到2020年预计建成1300万吨/年的规划目标,总体进展也滞后了。

China's consumption of oil was 756 million tons in 2024 and its production 213 million tons. It is nigh impossible to expect the 543 million ton discrepancy to be replaced by increased oil imports from Russia or from friendly countries that have overland pipelines to China.
A lot of that is exporting refined oil to the likes of Europe, especially now that they can't directly buy from Russia.
A "war economy" is not a medium- or long-term solution and if a hypothetical oil embargo/blockade is imposed on a long-term basis, this would be nothing short of disastrous for China's security. Additionally, I don't expect China to adopt a total war economy for a smaller conflict such as one involving Taiwan or the SCS region.

The US and Europe have a tendency to switch to other sources when an embargo or sanction is imposed; their energy demands could be met by US oil exports while other consumer goods are being increasingly Vietnamese- or Indian-made. As China transitions to a services-based economy, the effect of sanctions and blockades become more pronounced on its economy.
These two paragraphs are mutually exclusive. If US blockades China, China will blockade US. So how do you switch to Vietnam or India when China blockades those routes?
The US does not technically need Pacific bases to mount attacks on China's mainland; its B-2 & B-21 bombers could fly directly from CONUS and its submarines are mostly capable of launching land-attack cruise missiles. To a lesser extent, carrier-based aircraft could also launch the JASSM-ER from standoff ranges while staying out of range of most Chinese area denial weaponry.
Launching 100s of missiles to temporarily get through to 1 coastal airbase that can be repaired quickly isn't exactly sustainable though. There's 100s of airbase on the coast alone.
Folks need to stop entertaining the idea that China would risk a nuclear exchange by attacking CONUS via space-based weaponry and ballistic missiles.
It won't risk a nuclear exchange because of China's clear commitment to not use WMDs first. Nevertheless, China runs into the same salvo math problem as US does. Costs way too much to blow up something in mainland US.

China will strike mainland US only for the psychological effect of forcing US to base defenses there. Its a profitable trade because China always has massive defenses deployed in their mainland regardless of situation, while US doesn't. Having to keep defenses at home in China's default state, while for US, it would be wasting defenses they can put on the front line.

But neither US nor China can strike the respective core territories for anything more than psychologic effect. The battle will be in the no man's land between both countries.
See my above response to vincent.

Yes, but the discussion is about the effect of international sanctions or a US-led naval blockade against China. The smaller countries may indeed be more import-dependent than China, but (1) they wouldn't be sanctioned or blockaded in the event of a Pacific conflict and (2) China would care far more about its own economy and security situation than what is being done to the smaller countries, especially if these effects impact its chance of success in the said conflict.
How does such an international sanction take place? Any willing participant would be committing an act of war aggresson, while if there's a lot of unwilling participants (I.e. USN going around destroying their ports and ships), US would effectively be declaring war on most of the world.

If say Philippines or Indonesia blockade China, how do they avoid being devastated by China's own blockade or straight up counterinvaded? Remember these countries have nearly no air or sea drone defenses. Will US foot the bill to give them all China/Israel level defenses? I don't think that is too realistic since US will be stretched thin on defenses guarding it's existing bases alone.

A key difference in the balance of power between the US and China is that the US would be able to degrade China's industrial capacity (including manufacturing and shipbuilding) because it is capable of attacking China's mainland, whereas China's ability to influence US industrial and production capabilities - which will undoubtedly increase in wartime - would be minimal or nil.

I used to think the same way a few year ago.

1. But then Patch helpfully outlined what the US could realistic deliver in terms of munitions salvoes, and how Chinese air defences should be able to deal with these. The balance of power has only moved sharply in China's favour since then.

2. I used to think the US had the capability to ramp up my military production. But given what we've seen since the start of the Ukraine war, it's clear that the US doesn't have the supply chain nor personnel. In comparison, China would have surplus industry and personnel to rapidly pivot towards war production.

3. In terms of shipbuilding, the US Navy has struggled for over 10 years now to ramp up shipbuilding. As the US Navy presentation notes, China has 232x the shipbuilding capacity. So let's say Chinese shipbuilding is degraded by 90% whilst US shipbuilding doubles. China would still have a 11x advantage in shipbuilding.

4. In terms of semiconductors today:
a) the US+Europe only accounts for 19% of global semiconductor production
b) China is about 24%
c) another 51% is in combined Taiwan, Japan and South Korea

Yes, fabs are vulnerable, but that applies equally to the fabs in Taiwan, Japan and South Korea who make up 51% of global production.

We already looked at bombers operating from Hawaii previously

Even if you took the entire US tanker fleet (500 aircraft) and based it out of Hawaii, you'd be lucky to get 30 bomber sorties per day. There would be daisy chains of tankers refueling tankers refueling tankers.

Plus all those tankers and bombers would be packed in a small space in Hawaii, and would be a highly tempting and vulnerable target.

Then think about the realistic salvo sizes that bombers and submarines could realistically launch.

Then compare against the likely defences and the numbers of airbases and other aimpoints in China.

1. Public transport
Chinese cities are built around public transport eg. trains, subways, buses.
These have already gone electric and additional services can be run.

2. Cars/taxis
Car ownership levels are low, partly because cheap taxis are widely available. Taxis have already gone electric.
Note that the majority of new car sales are now electric as well.
Existing private electric cars can be repurposed as taxis.

3. Motorcycles
Electric motorcycles have replaced combustion engine motorbikes as well.
They will likely see a sales rennaisance, and probably be the better and cheaper option compared to a car anyway.

4. Aviation
Generally speaking, the high-speed railway system has already replaced airplane flights up to 2 hours in duration.
For longer duration flights, it just means a longer journey time. But remember that the ticket costs less and you typically have space to work or sleep. There's significant available capacity for more trains and passengers

5. Heavy equipment
This doesn't actually account for much fuel consumption.
And in any case, this is already going electric because it is more cost-effective

Math doesn't check out. How much of China's oil was already from Russian/friendly countries? They don't need to increase by 543m tons; they need to increase by 543m- what they already send to China. And that's assuming that China's usage is stable. If the US/West wants to embargo us, no need to make things for them; their economies can suffer than. China's domestic demand can further be decreased by replacing ICE cars with electric and finally, China has supposedly 1 year's reserve in fuel for just in case. How long can Western economies survive with a ban on Chinese goods?
A "war economy" is not a medium- or long-term solution and if a hypothetical oil embargo/blockade is imposed on a long-term basis, this would be nothing short of disastrous for China's security.
It would be worse for them as the Western standard of living drops even further and China trades with the global south.
Additionally, I don't expect China to adopt a total war economy for a smaller conflict such as one involving Taiwan or the SCS region.
That's wrong. We are willing to go to full nuclear extinction war as a matter of principle on this.
The US and Europe have a tendency to switch to other sources when an embargo or sanction is imposed; their energy demands could be met by US oil exports while other consumer goods are being increasingly Vietnamese- or Indian-made. As China transitions to a services-based economy, the effect of sanctions and blockades become more pronounced on its economy.
The US and Europe have a tendency to screw themselves over with either reduced standard of living and/or buying the same Chinese things repackaged through transit countries, increasing the costs on US consumers.
The US does not technically need Pacific bases to mount attacks on China's mainland; its B-2 & B-21 bombers could fly directly from CONUS and its submarines are mostly capable of launching land-attack cruise missiles. To a lesser extent, carrier-based aircraft could also launch the JASSM-ER from standoff ranges while staying out of range of most Chinese area denial weaponry.
That's all out war. We can launch land to land hypersonics at NY to Los Angeles in that event. We have the nuke subs too. We will not let them touch our land without dealing higher damage to theirs.
Folks need to stop entertaining the idea that China would risk a nuclear exchange by attacking CONUS via space-based weaponry and ballistic missiles.
You need to stop pretending that China didn't declare that it will go to nuclear war over Taiwan.

You need to stop making all this shit up about the US attacking the Chinese mainland with B1 and B2 when in actuality, the US just replaced its own Taiwan's webpage with an affimation of the One China Policy and we have new politicians entering office saying that Taiwan isn't worth a single US soldier because it will eventually return to Beijing.
Yes, but the discussion is about the effect of international sanctions or a US-led naval blockade against China. The smaller countries may indeed be more import-dependent than China, but (1) they wouldn't be sanctioned or blockaded in the event of a Pacific conflict and (2) China would care far more about its own economy and security situation than what is being done to the smaller countries, especially if these effects impact its chance of success in the said conflict.
The effect of sanctions is that the Western economies tank themselves. The effect of naval blockades is that the USN gets chased and hunted down as China expands the size of oceanic space it goes through. If America needs to resort to piracy/terrorist fighting, it has already lost and is just hanging on as a final FU before it departs as the leading global power.
A key difference in the balance of power between the US and China is that the US would be able to degrade China's industrial capacity (including manufacturing and shipbuilding) because it is capable of attacking China's mainland, whereas China's ability to influence US industrial and production capabilities - which will undoubtedly increase in wartime - would be minimal or nil.
No, that is countered by a matter of will. If China's facilities are struck, it is no longer a limited war. We will not allow a technicality, that the US can use planes while we need to use intercontinental missiles, determine what can and cannot be hit. If they hit us, we hit them back harder. If we leave the world to Russia after annihilating each other, so be it. Once they see that, once they are struck with our hypersonics and they realize we're not going to be bound by a technicality, perhaps even without out it as we warn them that it will definitely happen, it is the US calculus that will say this war isn't worth it.

Already addressed above in first paragraph.

What good are they? No one can replace Chinese manufacturing power.
Not possible as of now
Other user addressed. Also first paragraph addressed.
Well,good luck with that
Don't need luck; need Chinese manufacturing power.
