"The international community knows clearly whether the U.S. is the biggest contributor to the UN." That was the response of Chinese Foreign Ministry spokesman Zhao Lijian to U.S. Secretary of State Mike Pompeo's claim that the U.S. is the UN's largest contributor and the world body cannot survive without American leadership.

Zhao made the remarks during a regular press conference on January 13.

He also emphasized that international cooperation should be strengthened among countries to deal with global challenges.
