New Delhi: India has lodged a strong protest with China for issuing stapled visas to Indian nationals from Arunachal Pradesh and termed it "unacceptable", adding that New Delhi reserves its right to suitably respond to such actions, Ministry of External Affairs said on Thursday.

"This has been something that we have discussed many years ago. Our longstanding and consistent position is that there should be no discrimination or differential treatment on the basis of domicile or ethnicity in the visa regime for Indian citizens holding valid Indian passports," Ministry of External Affairs official spokesperson Arindam Bagchi said.

There have been reports that China has issued stapled visas to people from Arunachal Pradesh, who were due to participate in an international sporting event in China.

"It has come to our notice that stapled visas were issued to some of our citizens representing the country in an international sporting event in China. This is unacceptable. And we have lodged our strong protest with the Chinese side reiterating our consistent position on the matter and India reserves the right to suitably respond to such actions," he added.

According to reports, three members of India's Wushu team were not able to travel to China as they were issued a stapled visas since they are from Arunachal Pradesh.
