WASHINGTON: President Donald Trump on Monday offered to mediate the decades-long Kashmir dispute between India and Pakistan, signaling a shift in long-standing US policy that the issue must be solved bilaterally.

"If I can help, I would love to be a mediator," Trump said at the White House, where he was hosting Pakistan's Prime Minister Imran Khan. "If I can do anything to help, let me know."

It is far from the first time that Trump has offered to intervene in a seemingly intractable international dispute. US mediation, which has long been sought by Pakistan, is likely to be rejected outright by New Delhi.
