Trump needs a deal, but Xi needs it more
Although the substance of the Donald Trump-Xi Jinping talks are about tariffs, trade, supply issues (rare earth metals etc), fentanyl, Taiwan and most importantly Iran, the main purpose of the meeting for both leaders will be their future political survival. This is the essential subtext that you will probably not hear about from most legacy media. Xi needs a successful deal with Trump to show that he is still useful as Secretary General of the CCP Trump needs to bag wins soon to bring to prevent a Democratic sweep of Congress in November’s midterm elections. Lose both houses and the President can be sure that impeachment will follow.
