He made the comments while addressing a massive public gathering in Pakistan-occupied Kashmir's (PoK) capital Muzaffarabad to "send the world a message regarding the military curfew imposed in Indian occupied Kashmir", Geo News reported.
Calling the Kashmir situation a "humanitarian crisis", the Pakistan Tehreek-e-Insaf chief said that even the EU and British Parliament took up the issue.
"Today Kashmir has been internationalized. The UN Security Council held a meeting on Kashmir issue for the first time in 50 years. The EU, for the first time, said that the Kashmir issue should be resolved as per UN resolutions. The Organisation of Islamic Cooperation also said that India should lift curfew in Kashmir.
"More than 40 MPs in Britain raised the Kashmir issue. I am happy that US senators wrote a letter to President Donald Trump and urged him to intervene in the matter.
"The reason for me becoming an ambassador of Kashmiri people is that I am a Pakistani, a Muslim and a human... Kashmir issue today is a humanitarian problem.
"I am going to the UN General Assembly in New York and I will not disappoint the Kashmiri people," said Khan.
After India scrapped its Constitution's Articles 370 and 35A, which gave special status to Jammu and Kashmir, and divided the state into two union territories, Islamabad has been crying foul over New Delhi's move and continuously trying to highlight the issue on a global level.
Criticizing the Narendra Modi-led government in India, Khan said that "no matter how much violence is inflicted by the Indian Prime Minister it will not yield any success in the occupied valley".
He claimed that Modi was "pushing people towards extremism and peddling the agenda of RSS, which believes that only Hindus should reside in India".
Khan said that every Muslim around the world "was witnessing what brutalities being committed by the Indian fascist regime in occupied Kashmir", and added that the Indian Prime Minister was "provoking people" to go for extremism.
"Pakistanis are standing with the people of Kashmir this nation will fight till the end," said the cricketer-turned-politician.
A number of celebrities including Shehzad Roy, Faakhir Mehmood, Javaid Shaikh, Humayun Saeed and former Pakistan captain Shahid Afridi then riled up the crowd. Faakhir and Sahir Ali Bagga also performed at the rally.
Foreign Minister Shah Mahmood Qureshi, addressing the large gathering earlier, said that while "residents of Azad Jammu and Kashmir have access to news and Internet, occupied Kashmir was under a lockdown and a communications blackout".
He "challenged" the Indian Prime Minister to hold a rally like the one held in Muzaffarabad and address the residents of Srinagar.
Senator Faisal Javed, Information Minister Firdous Ashiq Awan, Defence Minister Pervez Khattak and Railway Minister Sheikh Rashid were in attendance, among others.
