United States Secretary of State Marco Rubio announced that the U.S. remains open to engaging in negotiations with Iran to end the ongoing conflict, but accused Tehran of not demonstrating a "serious" commitment to peace talks. Rubio made these remarks on Wednesday at an Association of Southeast Asian Nations (ASEAN) meeting in Manila.

The U.S. has been engaged in escalating conflict with Iran, with recent reports indicating that U.S. forces launched attacks against Iran for an eleventh consecutive night. These military actions have occurred amidst ongoing disruptions to crucial global energy transport routes, including the Strait of Hormuz.

Rubio emphasized that the U.S. is prepared for "positive and constructive negotiations and discussions, provided that the commitments made are honoured." He added, "The problem we’re having right now is that they’re not serious about talks. If they’re serious, we’re serious." He also stated that if Iran is not serious, the U.S. will "do what’s necessary to protect our interests and also the interests of our allies."

Rubio specifically addressed Iran's actions concerning the Strait of Hormuz, calling Iranian control over the international waterway a "dangerous precedent." He argued that any nation state asserting the right to control such a passage, impose tolls, and threaten ships creates a model that could be replicated elsewhere. "At its core, it’s very simple. Iran demands the right, which they do not have under any existing legal mechanism, to control the transit of traffic through the Strait of Hormuz," he stated, highlighting a fundamental threat to freedom of navigation.

During the ASEAN meeting, Rubio also discussed the strategic importance of the U.S. relationship with Southeast Asian nations, characterizing it as a matter of national interest. He expressed his belief that the region's developments will significantly shape the narrative of the 21st century, underscoring the interconnectedness of security and prosperity between the U.S. and Southeast Asia.

These statements come shortly after U.S. President Donald Trump renewed threats to target Iran's nuclear facilities at Natanz. Iran's military command responded by stating that such an attack would be considered an "expansion of war in the region" and could provoke retaliatory strikes against "all the interests of America, its allies and supporters."

The ongoing conflict and diplomatic posturing highlight the volatile geopolitical situation in the Middle East. The U.S. maintains its stance on ensuring freedom of navigation and protecting its interests, while Iran signals a readiness to respond forcefully to perceived aggression.

Unresolved questions remain regarding the specific conditions under which Iran might be considered "serious" about negotiations and the potential de-escalation pathways in the current tense environment.
