This means that from the political angle, there is probably enough to satisfy Washington over being seen, via a BIT with China, to be imposing labor welfare and environmental conditions, while China will probably accept some US-based arbitration and commitments to IP. If so, then much of the remaining text will be purely trade related.
The US trade lobby has also been much bruised during the trade war. Giving US corporations better protection and access to the China market via a US-China BIT would do Trump’s voter base a power of good. With the politics and voter base seemingly aligned, a US-China bilateral investment treaty may arrive on the US-China trade horizon sooner than expected.
