After a 72-hour deadline expired, American diplomatic staff have left their consulate in the Chinese city of Chengdu.

This new development has occurred after China ordered the closure in response to the US closing the Chinese consulate in Houston, Texas, last week, BBC reports.

Other activities that took place also, was the lowering of US flag, removal of plaque and staff leaving the consulate premises, before Monday’s deadline.

Reacting to the move, China’s foreign ministry said Chinese staff entered the building after the deadline and “took over”.

Comments also came from the US state department spokesperson who said: “The consulate has stood at the centre of our relations with the people in Western China, including Tibet, for 35 years.

“We are disappointed by the Chinese Communist Party’s decision and will strive to continue our outreach to the people in this important region through our other posts in China.”

The effects of the closure started as crowds of local residents gathered outside, with many waving Chinese flags and taking selfies.
