My guess is that the Chinese exchanges will follow too as they also need capacity for the exact same reasons.
My guess is that the Chinese are not going to be bullied by the US and there is no actual need for the capacity (as trading on exchanges is not done on the blockchain).
Very few people are actually using BTC for normal txs - it is simply not convenient and the fees to get your BTC make it actually a stupid idea (this whole argument about needing more volume of txs is actually just rubbish).
