Trump's announcement came after an expected trip by Vice President JD Vance to Pakistan for a peace talks with Iranian officials was put on hold.

Donald Trump said Chinese President Xi Jinping offered to help the US negotiate with Iran to reopen the Strait of Hormuz. Trump told Fox News that China’s heavy dependence on Gulf oil makes Beijing eager to keep the crucial trade route open and stable as tensions continue to rise in the Middle East.

The United States and Iran have signalled they will hold a new round of ceasefire talks in Pakistan, two regional officials said Tuesday, as leaders on both sides warned they were prepared for more fighting if a fragile two-week truce expires without a deal.

The extension was announced just hours before it was set to expire. The president did not provide details on how long the new ceasefire extension will last.

US President also said he would continue the US Navy's blockade of Iran's trade by sea, considered an act of war by Tehran

President Donald Trump huddled with his national security team Tuesday afternoon at the White House facing a major decision: what to do next with Iran.

As it remains uncertain whether Tehran will return to the negotiating table, Trump warned the U.S. will resume its assault of Iran if talks don't progress.

With a two-week ceasefire set to expire and Iran balking at the resumption of peace talks, President Trump said he would be extending the deadline to allow for Iran to "come up with a unified proposal.

Trump and Iran remain locked in a tense stalemate with dueling blockades as the ceasefire falters and nuclear deal negotiations hit a dead end.
