China is making “extraordinary concessions” to America in the dramatic trade war between the two superpowers, according to one of President Donald Trump’s key advisers.

A lifelong China obsessive, Michael Pillsbury has worked as a CIA spy, fed information about the Soviets to Henry Kissinger and developed defence strategy for Ronald Reagan. The 73-year-old is now director of Chinese strategy at the Hudson Institute, a think tank.

Pillsbury has become known as Trump’s China muse and been brought into the president’s inner circle to develop strategy for the standoff with President Xi Jinping.

Last week, China started buying American soya beans for the first time since the trade war began in July.
