The long-running economic battle between the world's two biggest economies has escalated. This week US President Donald Trump brought tariffs against China in an effort to strongarm the growing superpower into submission and strengthen American markets. But Beijing hit back, raising its own tariffs, escalating a trade war that could have implications for both countries. Trump is betting that tariffs will make America, and American people, richer. But does anyone win in a trade war? On this episode, Lucy Hockings speaks to the BBC’s Asia Pacific editor Micky Bristow, and Ritika Gupta, a North America business correspondent, about why Trump loves tariffs and what impact a trade war between China and America could have on the global economy.
