China calls for cool heads between US and Iran as blockade may affect its oil flows

China urged calm and restraint by all sides on Monday, following US President Donald Trump's threat to blockade the Strait of Hormuz after the failure of weekend talks in Islamabad aimed at ending the Iran war.

Before the war, most Iranian oil exports were shipped to China, the top global importer of crude.

Keeping the key Strait of Hormuz waterway safe, stable and unimpeded served the interest of the international community, foreign ministry spokesperson Guo Jiakun told a regular press conference, when asked about the blockade threat.

"China hopes the relevant parties will abide by the temporary ceasefire arrangements, remain committed to resolving disputes through political and diplomatic means, and avoid a resumption of hostilities," he said.
