"Such actions could lead to higher US inflation and quickly impact the rest of Asia, which has become increasingly integrated into a China-centric pan-regional supply chain," Roach warned.
The economist attributed the protectionism of the US Congress to a lack of knowledge of China. "They need to understand that 30 years ago China was on the brink of collapse.

"China needs to know the policy of Washington is very difficult. If you don't want to move aggressively in currency, that's fine. But arguments won't end if both sides don't agree to make a change," he said.
