Just a thought.
With international relations between China/Russia and the United States, (dont want a political discussion here, just stating reality), why doesnt China seem to show any interest for the Tu-160 Blackjack.
There are approximatelly 30 of these aircraft in service with the Russian Air force and they are highly regarded, powerful aircraft.
The Tu-160 is the worlds most powerful strategic strike aircraft, based on the design of the American B-1 bomber, it is larger, has a significantly increased range and warload.
It would not be too hard for China to purchase the blueprints for this aircraft as well as to bring in all the relevant russian engineers and simply build the things as fast as they can.
Im sure there would be a nice little cash bonus on the side for the Russians, maybe even an offset deal where new Russian Blackjacks where co-produced in Chinese factories and then balanced against the equity built on licence fees for the Chinese aircraft.
Net result is that China gets a large force of strategic buclear/conventional bombers, Russia gets some cash (behind the scenes) as well as a smaller force of the bombers to give it a moderate increase compared to the current numbers.
As well as this the Chinese would also be able to operate major servicing centers on the mainland where both russian and chinese aircraft can get serviced. This would save the cash strapped russians a lot of money and at the same tims give the Chinese immense experience in maintaining large complex airframes to western standards.
Obviously this should follow the signing of either a non-aggression pact or a full blown alliance between the two nations, but that again is a political question.
