US Secretary of State John Kerry is fine-tuning plans for an upcoming trip to Asia which is set to focus partly on climate change, his spokeswoman said Wednesday.
Although no dates have yet been released, the US top diplomat revealed at the weekend that he planned to return to China in the coming weeks.
In a tweet on Tuesday, Kerry said he had just met with Assistant Secretary for Asia Danny Russel and climate chief Todd Stern before his upcoming trip as climate change will be "a major theme."
It will be Kerry's fourth trip to Asia as the US administration seeks to "rebalance" towards the region, but State Department spokeswoman Jen Psaki had no dates to announce saying only that "planning is ongoing."
She acknowledged however global warming would be one of the issues on the agenda.
