China said on Tuesday it will provide humanitarian assistance to Middle Eastern countries, including Iran and Lebanon, targeted in US and Israeli strikes in the conflict now in its third week.

China’s foreign ministry spokesman Lin Jian said the war had caused “grave humanitarian catastrophes” in Iran and other Middle Eastern nations.

“China has decided to provide emergency humanitarian assistance to Iran, Jordan, Lebanon and Iraq. It is hoped this will help alleviate the humanitarian plight faced by the local populations,” Lin told a press conference, without providing further details.

“China will continue to make every effort to promote peace and stop the war … and to prevent further spreading of the humanitarian crisis,” he added.

China has sought to mediate in the war, with its special envoy to the Middle East, Zhai Jun, urging de-escalation when he recently met Saudi Arabia’s foreign minister for talks.

China’s top diplomat, Wang Yi, has also said that the war “should never have happened” and called for an end to fighting.

The humanitarian aid announcement came after US President Donald Trump said he would delay a planned visit to Beijing.

Trump, who postponed his planned visit to Beijing due to the war, according to the White House, has also pressured China to help Washington reopen the Strait of Hormuz.

The vital sea passage, through which a fifth of global oil supplies normally pass, was effectively closed by Iran in retaliation to US and Israeli strikes.

During the press briefing on Tuesday, China’s foreign ministry spokesman also rejected US media reports that earlier claimed that Trump would delay his visit to China, if the country did not assist with the reopening of the Strait of Hormuz.

“We noted that the US has publicly made clarifications on the misguided media reports, calling them completely ‘false’. The US side stressed that the visit is not linked to the issue over the Strait of Hormuz,” he said.

“Both China and the US are maintaining communications on Trump’s visit to China,” he said, without providing further details.
