Non-resident senior fellow John Lee spoke to CNN about the the meeting between Donald Trump and Xi Jingping on the sidelines of the G20 Summit in Argentina where it was agreed to place a halt on new tariff measures between China and the US. While Trump has touted this as an acheivement, Dr Lee says we are merely next phase of what will be an enduring economic competition between the world's two largest economies. "For America, the next 90 days is about assessing testing how much further China is prepared to compromise," he writes.
