However, staff returned to work after police checked the vehicle, WTO spokesperson Xu Ankai said.
He said that around 12.55 p.m., security guards of the WTO headquarters found the suspicious vehicle outside the main building but could not make sure what was inside.
Some of the WTO staff were evacuated for security reasons. They later went back to work after police with a sniffer dog found nothing.
The spokesperson said the WTO had not received any bomb threat.
