Beijing: A few days after China blocked a ban on dreaded terrorist and Jaish-e-Mohammad chief Masood Azhar in the United Nations, India has hit back by reportedly allowing World Uyghur Congress (WUC) leader Dolkun Isa to visit the country.

New Delhi's decision to permit Isa and his associates, whom China regards as backers of terrorism in its volatile Muslim-dominated Xinjiang province, has not gone down well with Beijing. Isa will attend a conference from April 28 to May 1 at Dharamsala, the seat of the Tibetan government-in-exile, in Himachal Pradesh.

China does not recognise the Tibetan government-in-exile and has been very critical of India's stand on Dalai Lama.

China on Thursday aired its concern over Isa's reported visit to India, saying he is a "terrorist" on Interpol's Red Corner and it is the obligation of all countries to bring him to justice.

"I am not aware of the situation, " Foreign Ministry spokesperson Hua Chunying said, when asked about the reports that WUC, leaders including Isa, were given permission to meet the Dalai Lama later in April.

"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," Hua said.

Xinjiang, which has over 10 million Uyghur population of Turkik origin Muslims, was on the boil for several years over Uyghur protests against the large-scale settlements of Hans from different part of the country.

China blames East Turkistan Islamic Movement (ETIM), a militant Islamist group, for terrorist attacks in Xinjiang and other parts of the country.
