US, China agree to cooperate on climate crisis

The United States and China, the world's two biggest carbon polluters, agreed to cooperate to curb climate change with urgency, just days before President Joe Biden hosts a virtual summit of world leaders to discuss the issue.

The agreement was reached by U.S. special envoy for climate John Kerry and his Chinese counterpart Xie Zhenhua during two days of talks in Shanghai last week, according to a joint statement.

The two countries "are committed to cooperating with each other and with other countries to tackle the climate crisis, which must be addressed with the seriousness and urgency that it demands," the statement said.

China is the world's biggest carbon emitter, followed by the United States. The two countries pump out nearly half of the fossil fuel fumes that are warming the planet's atmosphere. Their cooperation is key to a success of global efforts to curb climate change, but frayed ties over human rights, trade and China's territorial claims to Taiwan and the South China Sea have been threatening to undermine such efforts.

Meeting with reporters in Seoul on April 18, Kerry said the language in the statement is "strong" and that the two countries agreed on "critical elements on where we have to go." But the former secretary of state said, "I learned in diplomacy that you don't put your back on the words, you put on actions. We all need to see what happens."

Noting that China is the world's biggest coal user, Kerry said he and Chinese officials had a lot of discussions on how to accelerate a global energy transition. "I have never shied away from expressing our views shared by many, many people that it is imperative to reduce coal, everywhere," he said.
