Beijing has rejected Washington`s latest demand that countries join a renewed campaign of economic sanctions against Iran, reaffirming that the escalating crisis requires political dialogue.

"Sanctions and pressure tactics are not the solution," Chinese Foreign Ministry spokesperson Lin Jian told reporters on Thursday.

The rebuke came one day after the Trump administration issued an open call to allies and China alike to fall in line with what the president billed as the "most crushing economic operation ever taken against any country"-a boastful threat that came after Washington failed to achieve any of its war objectives military some six months after starting the aggression on Iran in late February.

Notably, the United States has yet to detail the full scope of its so-called operation, with US Secretary of Treasury Scott Bessent punting further specifics to a Monday press conference-a delay that raises questions about the campaign`s actual readiness.

China calls on parties to act responsibly and stick to the political and diplomatic approach, added Jian.

Iran has strongly condemned the US campaign, with Minister of Foreign Affairs Abbas Araghchi describing Washington`s economic aggression as an attempt to divert attention from America`s own problems.

Araghchi pointed to America`s "unprecedented debt & surging interest costs" as Washington seeks to impose further economic pressure on Iran.

Iran`s Ministry of Foreign Affairs said on Thursday the latest US sanctions, announced on the anniversary of the 1953 coup against Iran`s democratically elected government, demonstrate Washington`s continued hostility toward the Iranian people.

"The new US sanctions are not only another indication of the continuation of 73 years of hostility by US policymakers toward the Iranian people, but also demonstrate the anti-human, lawless and hegemonic nature of the US government," the ministry noted.

The ministry further condemned the sanctions for targeting the fundamental rights of Iranian citizens and violating international norms.

"Without a doubt, the US economic sanctions against Iran, which target the fundamental human rights of every Iranian citizen, constitute ‘economic terrorism` and ‘crimes against humanity,`" it mainiated.

Beijing`s rejection comes ahead of Chinese President Xi Jinping`s planned September 24 visit to the White House, adding significance to China`s refusal to participate in Washington`s economic campaign against Tehran.
