Disastrous consequences: Imran Khan warns Donald Trump over war with Iran
On asking what was Donald Trump's reaction to it, he said that the US President did not mention anything but he is sure that he must have understood what has been told.
"Afghanistan is yet to be resolved and Iran would be much bigger (if war starts)," Khan said.
Donald Trump and Imran Khan held a meeting on the sidelines of World Economic Forum (WEF) summit on Tuesday.
The tensions between Iran and America had escalated after the US Army killed a powerful Iranian commander General Qasem Soleimani on January 3.
"If there is conflict between Iran and the Western world it will be a disaster - it will cause poverty in the world - and who knows how long it may go on. In my opinion it would be insanity," Khan said.
"I spoke to President Trump yesterday and I told him it would be a disaster," Khan said.
After meeting with Imran Khan, Donald Trump had said that the US is watching closely the development between India and Pakistan relations; he once again offered to mediate and help on the Kashmir issue.
Trump told Khan, whom he referred to as "my friend", that he would speak to Prime Minister Narendra Modi about the ongoing Kashmir issue. Trump is expected to visit India in the coming weeks, marking his first visit after assuming office.
"What's going on between Pakistan and India … if we can help, we certainly will be willing to. We have been watching it very closely and it's an honour to be here with my friend," Trump had said.
"The Pakistan-India conflict is a very big issue for us in Pakistan and we expect the US to always play its part in deescalating the tensions, because no other country can," Khan had said.
