U.S. President Donald Trump and Chinese President Xi Jinping reportedly addressed the Strait of Hormuz and Iran’s nuclear program amid rising tensions between Tehran and the UAE during a contentious BRICS meeting.

According to the White House, Trump and Xi held a "good" meeting on Thursday in which they agreed that the Strait of Hormuz "must remain open", The Caspian Post reports, citing The New Arab.

"The two sides agreed that the Strait of Hormuz must remain open to support the free flow of energy," the White House said.

According to the White House, Xi expressed an interest in purchasing more American oil to reduce China's dependence on the strait in the future.

Beijing's own readout of the meeting did not mention any such interest.

Meanwhile, Iran's foreign minister accused the United Arab Emirates of direct involvement in military operations against his country during a BRICS meeting in New Delhi on Thursday, Iranian state media reported.

The spat comes a day after the UAE denied a statement by Israeli Prime Minister Benjamin Netanyahu that he visited the Gulf country during the Iran war, to which Araghchi already reacted by saying that "those colluding with Israel to sow division will be held to account."

"I didn't name the UAE in my (BRICS) statement for the sake of unity. But the truth is that the UAE was directly involved in the aggression against my country. When the attacks started, they didn't even issue a condemnation," state media quoted Araghchi as saying on Thursday, in response to comments made by the Emirati representative.

Iranian state media did not specify what the Emirati representative said.

According to the reports, Araghchi argued that neither US bases nor an alliance with Israel provided the UAE with security and that it should reconsider its policy toward Iran.
