US President Donald Trump is close to a decision on how to respond to what he considers China’s unfair trade practices, a senior Trump administration official said on Tuesday. Trump is considering encouraging US Trade Representative Robert Lighthizer to initiate an investigation of Chinese trade practices under the 1974 Trade Act’s section 301, the official said. An announcement could come as early as this week, the official said, speaking on condition of anonymity. Section 301 of the Trade Act of 1974 allows the president to unilaterally impose tariffs or other trade restrictions to protect US industries from “unfair trade practices”
