The NSC has no doubt briefed President Trump that China's systemic weaknesses make her vulnerable, even fragile, and that China could implode into massive civil disorder. While this would end China's menace as a potential rival to the US, it would also disrupt the US and world economies, which have come to rely on the output of China's factories and its demand for natural resources as drivers of economic growth. Worse, a Chinese collapse would present a nightmare of a security challenge like that of the Soviet collapse as China's weapons and technical talent went onto the black market and her internal rivals brandished nuclear weapons at each other.
The election of Donald Trump was not only a blessing to us dear Americans, but a blessing to the entire world...I believe the Trump admin will make deals in ways that serve our interests, but also prevent catastrophes for offending parties (like China) - yet pave the way for freedom to emerge organically from within those countries...as can be seen right now in Iran. (All the protests and uprisings!)
A long way to go, but still a sign of things to come...
