President Xi has hardened his stance by rallying his nation for the new long march.  This is a dramatic sign that China won't relent in the US-China trade war and won't sign any humiliating trade deal.  This is significantly different from the previous meek stance put up by the Chinese.

Thus, the US can forget about bulldozing its way into China now.  The US-China trade talk has broken down officially now.
