US Special Presidential Envoy for Climate John Kerry's recent visit to China concluded without a significant climate agreement. Despite "frank" discussions, Kerry announced that further negotiations are needed between the two largest global polluters.

Kerry emphasized the intention to "unstick" stalled dialogue, acknowledging the need for "a little more work" to finalize a deal. He expressed optimism about the possibility of reaching an agreement, stating that both nations believe it's "doable."

The discussions represent a resumption of climate talks after a year-long pause following former House Speaker Nancy Pelosi's visit to Taiwan. Kerry's office confirmed the quiet restart of talks in May, with plans for in-person meetings.

While Kerry has engaged in private talks with Chinese officials since assuming his role, including two meetings in China in 2021, his position and negotiations have drawn criticism from Republican lawmakers. They question the authority of his role, which doesn't require Senate confirmation, and express concerns about the implications of his dealings with China.

House Oversight Committee Chairman James Comer has initiated an investigation into Kerry's office and its negotiations with China. He has expressed concerns about the Biden administration's approach to China and its potential impact on American interests. Other Republican figures like Rep. Elise Stefanik have also voiced criticism, highlighting China's actions and questioning the administration's focus on climate discussions amidst these concerns.
