Unprecedented rapacity by the United States - not only forced tech transfer, and then having to pay for the privilege of being robbed; the hegemon is consuming its vassals, as it withdraws from its commitments.
The second China becomes powerful enough to throw their military around like the US is when I start supporting tech transfers the other way. A more distributed power structure is much better for overall progress.
This would be late timing.
Ask yourself what the benefit is of having the US as a diplomatic partner if you can get the same deal from China but with a more stable and predictable leadership.
