Treasury Secretary Steven Mnuchin is leading a delegation of USA officials.
"It's a big, big challenge".
Consultation between China and the United States on economic and trade issues will be constructive as long as the US delegation comes with sincerity, said a Chinese Foreign Ministry spokesperson Wednesday. "It has not worked well for us".

"Our trade deficit is too big and too continuing, too chronic and too inspired by evil practices", he added, emphasizing the Trump administration's focus on the trade imbalance.
