According to media reports, Isa was granted E-visa on April 16 which was cancelled on April 23 by Indian immigration.
Isa, who lives in Germany was scheduled to visit India by month end to participate in a conference in India to discuss democratic transformation in China.
The conference is being organised by the US-based 'Initiatives for China'. The Dalai Lama is also expected to attend the event.
China who was unhappy over Indian move of granting visa to Isa, has contended that he is a terrorist who has an Interpol red corner alert issued against him.
"What I want to point out is that Dolkun is a terrorist in red notice of the Interpol and Chinese police. Bringing him to justice is due obligation of relevant countries," Chinese foreign ministry spokesperson Hua Chunying was quoted as saying on Indian move.
The granting of visa to Isa, appeared to be a message to China which recently blocked a move in the UN to ban Maulana Masood Azhar, the chief of the Jaish-e-Mohammad. China not only blocked the ban on the insistence of Pakistan, but even lectured India on being good neighbours.
