Seeking China’s help on isolating North Korea through economic sanctions, Trump backed off a threat to label China a currency manipulator. He was off-and-on conciliatory on trade during an extended visit to Asia in November, and China announced it would lift restrictions on foreign investment in its banks and other financial institutions.
