Which country keeps going back on its own word?

Editor's note: During the recent 11th Sino-US high-level economic and trade consultations, the United States announced that it would raise the tariffs on $200 billion worth of Chinese goods from 10 percent to 25 percent. Zhong Sheng, a columnist for People's Daily, comments:

Besides the tariff hike, the US also labeled China as backsliding from and reneging on the commitments it has made, claiming China's "backtracking" has weakened the core interests of the US.

The "backtracking" accusation fabricated by the US completely confuses black and white. Over the past more than one year, China has been pushing forward Sino-US economic and trade consultations with utmost sincerity in the hope of reaching a mutually beneficial and win-win agreement on the basis of mutual respect. Even after the US threatened to impose tariffs on Chinese goods, the Chinese delegation still headed to the US for talks, which showed China's sincerity in pushing forward bilateral negotiations.
