Indonesian President Joko Widodo expressed pessimism on Tuesday that the United States and China will resolve their trade dispute when the leaders of the world’s two biggest economies meet at the G-20 summit in Argentina at the end of this week, Reuters reports. With only days  before the summit, US President Donal Trump renewed his threat of raising tariffs against Chinese goods in an interview with The Wall Street Journal.  The tariffs would be raised from 10 per cent to 25 per cent on $200bn worth of goods. Global trade tensions are putting at risk commitments by the Group of 20 leading economies to keep markets open, European Union delegates to the G20 said, pledging to help reform World Trade Organization rules to resolve the strains.
