BEIJING: US climate envoy John Kerry is set to kick off his second visit to China inside five months under China's invitation, at a time when the bilateral relationship has hit a nadir not seen in decades.

China's Ministry of Ecology and Environment announced on Tuesday that Kerry would visit China this week, under China's invitation. During his visit, Kerry will discuss cooperation on climate change between China and the United States and the upcoming 26th UN Climate Change Conference of the Parties (COP26) with his Chinese counterpart Xie Zhenhua in the Chinese city of Tianjin.
