The Financial Times reports that rivalry between the US and China was laid bare at the Asia Pacific Economic Co-operation meeting over the weekend, as Xi Jinping, China's president, and Mike Pence, US vice-president, sparred over trade and security. The tension between Mr Pence and Mr Xi at the Apec summit — which failed to issue a joint communiqué for the first time in its 29-year history — damped hopes that a detente between Washington and Beijing could be in store at the G20 world leaders summit in Argentina later this month. At the upcoming gathering in Buenos Aires, starting on November 30, the Chinese president is set to hold much-anticipated talks with Donald Trump, his US counterpart. Many investors and policymakers have been hoping that the encounter would yield a truce to stave off an escalation in the trade war between the two countries, one of the biggest clouds hanging over the global economy. Unless a deal is reached, US tariffs on $250bn of Chinese goods are scheduled to rise from 10 per cent to 25 per cent in January. Mr Trump has also threatened to impose levies on a further $267bn of goods from China, covering all imports.
