Speaking to reporters before his meeting in the White House with visiting Pakistan Prime Minister Imran Khan, Trump said: "I was with Prime Minister Modi two weeks ago, and we talked about the subject. And he actually said, 'Would you like to be a mediator, or arbitrator', and I said 'Where?', and he said 'Kashmir, because this has been going on for many, many years'. I was surprised for how long it has been going on."
Trump made the assertion answering a question from a reporter about what he would do to help resolve the Kashmir issue.
But before Trump answered, Khan said: "I will be asking President Trump (on Kashmir), the US can play the most important role in bringing peace in the subcontinent, which is held hostage to the issue of Kashmir."
"The most powerful state, the US, can solve the problem," he said, adding that he had "made overtures for dialogue with India" but to no avail.
Trump said that he was surprised at how long the Kashmir problem has been dragging on - and Khan interjected: "70 years".
Trump continued: "I think they (India) would like to see it resolved, and I think you (Pakistan) would like to see it resolved. And if I can help, I would love to be mediator."
"It's impossible to believe that two incredible countries that are very, very smart, with very smart leadership, can't solve a problem like that. But if you would want me to mediate, or arbitrate, I would be willing to do that," he said.
Khan then added: "I would like to tell you that right now you will have the prayers of over a billion people if you can mediate and resolve this issue."
To this, Trump nodded and said: "It should be resolved. But he (Modi) asked me the same thing. So I think there is something. So, maybe we'll speak to him, or I'll speak to him and we'll see if we can do something."
"Because I have heard so much about Kashmir. Such a beautiful name, it's supposed to be such a beautiful part of the world. But right now, there's just bombs all over the place. So everywhere you go, there are bombs.. And it's a terrible situation, been going on for many years. If I can do anything to help, let me know."
