China climate change cooperation not "favor" to the U.S. - U.S. national security adviser

White House National Security Adviser Jake Sullivan on Friday said the United States does not consider China's cooperation on climate change a favor.

"We are not in the business of trading cooperation with China on climate change as a favor that Beijing is doing for the United States," Sullivan said during Aspen Security Forum webinar. "We think action on climate change is a fundamental responsibility in every significant country in the world."
