“The Trump administration has appeared confounded by Beijing’s entirely anticipable reaction to Trump’s tariff escalation,” added Mr. Hass, who met with officials and analysts in China this month as Mr. Trump escalated the tariffs. “China’s leaders do not view tit-for-tat tariffs as an isolated trade issue that lends itself to a negotiated resolution.”
Mr. Xi would be reluctant to speak with Mr. Trump unless teams from the two nations first laid a foundation for top-level discussions. That would help ensure the outcome of a conversation is predictable, which is how diplomacy traditionally works.
