The Tu-22 production line from rumour could be an answer to shorten the gap to compensate the lack of offensive long range weapons.
Like some of the guys here, a modern China with her own indigenous adavnce avionics and radars could could the Tu-22MBs (some say it to be H-10) into an all new breed of bombers. This if it turns out true, the whole new fleet of H-10s could been seen as a game changer to the US Pacific policy to surround China with F22 and F35 as well as CBGs and troops. In order to counter China's new breed of H-10s, the US got to redeploy troops and add more logistics resources more weapon aids for her allies countries, which in turn needs money to finance these ops. For China, its a strategy of an answer to her own 'war of attrition' with the US in the pacific region.
Also with the increasingly focus of second artillery in missile attack, range and striking distance have achieved a new heights. But the second artillery is land based, mainly. The need of Tu-22s is to increase the chances of second strike capability before the full deployment of the Type 093 SSBNs which is still in research and development phase. Furthermore, as China seeks to gain a striking ability, to buy a nearly out of touch Tu-22 production line means a speeding up of researching on bomber tech.
Some might say with the H-6 already in services for more than 30 years, it is a capable airframe with modernised equipment, However, the H-10s would add extra delivery power to the PLAAF and PLANAF. What they have been done and gained experiences on the H-6 provides an all new lifeline for this outdated bomber. There are already examples in the USAF that refitting an airframe with advance aviation avonics plus cruise missile with conventional/nuclear warheads.
The capability is nice, but paying one and a half billion for a production line that's been out of work for twenty-plus years isn't.
As stated before, I'd be very excited if China joined in on the PAK DA project, with full cross-sharing of technologies to build a true supersonic stealth bomber--basically a larger, longer-range J-20. That would be a much more economical move, and avoid a lot of the deadweight.
