The president noted that the two had what he called a “long and very good call,” saying that a possible deal between the two nations is making good progress. A Reuters article says it’s been a rough 2018 for the world economy as the trade war between the two largest economies has disrupted the flow of hundreds of billions of dollars’ worth of goods. Trump and XI agreed to a 90-day truce that began on December 1st, while they attempt to negotiate a deal that would bring months of escalating tensions to an end. “Just had a long and very good call with President Xi of China,” Trump said on Twitter. “Deal is moving along very well. If made, it will be very comprehensive, covering all areas, subjects, and points of dispute. Big progress being made!” Chinese state media also reported the two had a phone conversation. Xi was quoted as saying teams from both countries are working to implement a consensus reached with Trump in Argentina. The Chinese Ministry says the countries have endured storms in their relationship before, but also say strong ties are important to both economies and to ensuring stability in the global economy.
