China hopes to work with other BRICS countries to continue to work for peace and stability in the Middle East, Foreign Ministry spokesman Guo Jiakun said on Wednesday.

Guo made the remarks after Brazil released a joint statement of the BRICS on the escalation of the security situation in the Middle East.

The statement issued on Tuesday said the BRICS is gravely concerned about the military strikes against Iran since June 13.

The attacks "constitute a violation of international law and the Charter of the United Nations, and the subsequent escalation of the security situation in the Middle East", the statement said, calling on all parties to engage through existing channels of dialogue and diplomacy.

"BRICS countries are a progressive force for maintaining world peace and stability and upholding international fairness and justice," Guo said at a regular news conference.

The statement plays a constructive role in easing tensions in the Middle East, Guo said.

In response to a question about how much Iranian crude oil China is importing, Guo said China will take reasonable energy security measures according to its own national interests.
