President Donald Trump postponed a Saturday press conference designed to tout the "great success" of the Group of 20 meeting in Argentina, citing the death of former president George H.W. Bush.
Via Twitter, the president said in Buenos Aires that he would wait until after his return to the United States to brief the press on the outcome of the confab between the world's largest industrialized nations.
The president's move came as markets were hopeful about a detente, or at least signs of progress, between the U.S. and China on trade. Trump and Chinese President Xi Jinping met at a rescheduled dinner, at which Xi reportedly told the president that the two countries should cooperate more and bolster ties.
G-20 leaders have agreed to address reform in the World Trade Organization (WTO), maintain current efforts on climate change, and progress taxation of the digital economy. However, the group sidestepped "taboo words" in drafting the communique that referenced protectionism or unfair trade practices. This was seen as important given the ongoing tensions between the United States and China.
The nation's 41st president died on Friday at the age of 94, and Trump designated December 5 as a national day of mourning. Despite Trump having risen to power railing against the Republican establishment embodied by Bush, the president and First Lady Melania Trump will attend a state funeral that will be held in the nation's capital.
