Relations between Washington and Beijing are fraught with trade, technology and human rights disputes.

US Deputy General Counsel John Kerry and his Chinese counterpart, Xie Zhenhua, will spend this week in Tianjin, a North China capital, looking for some much needed ground ahead of world-wide talks in Glasgow in November.

China, global’s largest source of greenhouse gases, has committed to peak emissions by the end of the decade and reduce it to zero by 2060.

Hopes of a breakthrough in Glasgow are highly influenced by China and the US being able to build momentum.

On Wednesday the Chinese foreign minister Wang Yi cautioned Kerry that deteriorating US-China relations had the potential to undermine cooperation between the two countries on climate change.
