U.S. President Donald Trump has intensified pressure on Iran, warning that military strikes remain a viable option as the Islamic Republic grapples with its largest wave of protests in years, eliciting a firm rebuke from China’s government over the use of force in the Middle East.

Trump’s remarks come as demonstrations sparked by deep economic grievances have spread across Iran and been met with a violent government response that rights groups say has left hundreds dead and thousands detained.

While the White House maintains that diplomacy is the “first option,” Trump’s advisers have stated that “very strong” military options, including airstrikes, are on the table should Tehran’s crackdown continue, and Washington has also imposed punitive tariffs targeting countries that continue trade with Iran.

Tehran has responded with warnings that any foreign military action would prompt retaliation, with senior officials asserting that Iranian armed forces would defend the nation and could consider U.S. and allied assets legitimate targets.

Amid these escalating tensions, China’s foreign ministry publicly opposed the use of force and external interference in Iran’s internal affairs, calling for restraint and urging all parties to seek peaceful resolution and stability.

Beijing emphasised its hope that Iran’s government and population can overcome their “current difficulties” and stressed opposition to interference in the domestic affairs of sovereign states.

The unfolding crisis has drawn varied international reactions, with European governments expressing concern over violence against protesters, while other global actors urge caution and de-escalation as diplomatic channels remain under strain but not entirely closed.
