Japan's Nikkei 225 rises to record high in mixed Asia trading as Trump extends Iran ceasefire

Japan's Nikkei 225 hit a record high Wednesday while the broader Asia markets were mixed as traders assessed the Middle East conflict outlook after President Donald Trump extended the U.S. ceasefire with Iran.

"Based on the fact that the Government of Iran is seriously fractured, not unexpectedly so and, upon the request of Field Marshal Asim Munir, and Prime Minister Shehbaz Sharif, of Pakistan, we have been asked to hold our Attack on the Country of Iran until such time as their leaders and representatives can come up with a unified proposal," Trump said in a Truth Social post.

He added that the ceasefire would be extended until Tehran submitted a proposal or discussions were concluded, and that the U.S. military would continue its blockade of Iranian ports.

However, the timeline remains uncertain. Negotiators from Tehran said they wouldn't attend the talks with the U.S., calling them a "waste of time," Iranian state media reported Wednesday.

The uncertainty also delayed Vice President JD Vance's trip to join peace talks, according to reports from Axios and The New York Times, citing U.S. officials with knowledge of the situation.
