The Chinese and Americans have different views of diplomacy and both sides have a lot to lose with a negative outcome from the meeting
The world’s democracies must act to save freedom and democracy. The US should support Taiwan's efforts at constitutional reform to achieve greater democracy and freedom. This would attract China's 1.4 billion people to call for democratization, and world peace would be the result. The prerequisite for the permanent world peace is democratization of China. While the CCP has always attempted to ruin Taiwan's freedom and democracy, Taiwan is the only entity capable of saving the Chinese people through democratization. See the Charter for Permanent Peace and Development / Global Unity Constitutional Standards.
