(Telecompaper) US President Trump and Chinese President Xi Jinping will be meeting at the Group of 20 industrial and developing nations in Buenos Aires, Argentina. The event, set to start on 30 November, will see the two world leaders continue discussions on trade and tariffs, after an unsuccessful round of talks earlier this fall. Trump told the Wall Street Journal that it is "highly unlikely" that he will accept China's request to postpone tariff increases and to impose tariffs on more goods. Trump also said a tariff of 10 percent could be placed on Apple iPhones and laptop computers imported from China. These had escaped earlier tariff rounds.
