Meanwhile, the US has sent a to-do list to China to reduce the trade imbalance between the world's two largest economies. That's according to a Wall Street Journal report on Monday. Trade Representative Robert Lighthizer reportedly asked China in a letter sent to Vice Premier Liu He to cut its tariffs on American autos, buy more US-made semiconductors and allow U.S. firms greater access to the Chinese financial sector. The newspaper also reported that Mnuchin was considering a visit to Beijing to pursue negotiations. The Trump administration signed a memorandum last week to levy as much as 60 billion US dollar tariffs on Chinese imports. The move triggered widespread fear of a massive trade war between the two countries.
