Ok pretty sure this is China's response
This is laughable response from China. When was the last time China ever enforced a so called sanction? Never ever. Yes, they have stopped buying or selling items to countries in the past. But never against individuals or organizations.
I did argue a day ago how China's response will be weak because it is in their best interest to keep the status quo and focus on the economy. Taiwan and US are so anti-China right now and so very much afraid of the future, that they would probably prefer the war now rather than later.
Its sad to see China behaving this weak but that's their best option now.
Trying to deflect to a weaker response by china in order to make your point but didn't work. Id say inspecting ships in the strait is a more aggressive and befitting response than the sanction.
