China on Tuesday warned against opening a “Pandora’s box” in the Middle East after the United States announced the deployment of 1,000 additional troops to the region amid escalating tensions with Iran.

Foreign Minister Wang Yi also urged Tehran to not abandon the nuclear agreement “so easily” after Iran said it would exceed its uranium stockpile limit if world powers fail to fulfil their commitments under the agreement in 10 days.

“We call on all parties to remain rational and restrained, not to take any actions to provoke the escalation of tension in the region, and not to open a Pandora’s box,” Wang told reporters in Beijing

“In particular, the United States should change its practice of extreme pressure,” Wang said.
