American diplomats are to leave the US consulate in the south-western Chinese city of Chengdu, following Beijing’s decision to close the mission.
With just hours to go before a Monday morning deadline, staff could be seen carrying box files and bags of rubbish.
Meanwhile, crowds of local residents have gathered outside, with many waving Chinese flags and taking selfies.
China acted in response to the US closing its consulate in Houston, Texas, last week.
After a 72-hour deadline for Chinese diplomats to leave the Houston mission expired on Friday, reporters saw men who appeared to be US officials force open a door to enter the premises.
US Secretary of State Mike Pompeo said Washington had decided to act because Beijing was “stealing” intellectual property.
Chinese Foreign Ministry spokesman Wang Wenbin responded by saying that the US move was based on “a hodgepodge of anti-Chinese lies”.
Tensions have been escalating between the two nuclear powers over a number of issues.
Chinese state media have been showing pictures of lorries leaving the US consulate, and workers removing diplomatic insignia from the building.

Dozens of Chinese police have been deployed outside, urging onlookers to move on and trying to prevent any provocations.
However, boos were heard when a bus with tinted windows left the building on Sunday, the AFP news agency reports.
When Chinese diplomats left their mission in Houston for the last time they were jeered by protesters.
The Chengdu consulate – established in 1985 – represented US interests over a vast area of south-western China, including the autonomous region of Tibet, where there has been long-running pressure for independence.
The majority of the diplomatic mission’s more than 200 employees had been hired locally.
With its industry and growing services sector, Chengdu is seen by the US as providing opportunities for exports of agricultural products, cars and machinery.
After the mission’s closure the US will have four consulates in mainland China and an embassy in the capital Beijing. It also has a consulate in Hong Kong, the former British colony.
China lost its Houston mission last week, but still has four other consulates in the US and an embassy in the capital Washington DC.
