Some U.S. lawmakers submitted a bill to the Congress on Tuesday, calling for a suspension of sales of law enforcement equipment by U.S. companies to Hong Kong including tear gas, pepper spray and rubber bullets.

"It is because of the indulgence and support by some U.S. politicians that the anti-China disruptors in Hong Kong are so reckless and unscrupulous,” said spokesperson of Chinese Foreign Ministry Hua Chunying on Wednesday, demanding them stop condoning violent criminal offenses and stop meddling in Hong Kong affairs immediately.
