The opposite was of course done when the US sold a ton of Xeon Phi accelerators to China when they built the Tianhe-2 supercomputer. My favourite conspiracy theory is that this was done deliberately by the US, since Xeon Phi was a large pile of steaming turd, so the Chinese wasted money on a machine with high theoretical FLOPS but crappy real world performance, and also wasted the time of their scientists and programmers who were porting code to a programming paradigm that went nowhere fast.
