Marpe Sora, a lecturer in Computer and Engineering Department of Rajiv Gandhi Central University, went on the tour of China with 21 other Indian academicians from November 24, the Head of the Department Dr S K Sharma said.

Sorpa is likely to return to India on Thursday night.

The university, in a press release here, described grant of visa to the Arunachalee lecturer as a 'breakthrough achievement'.

Early this year, the refusal of visa to an Arunachalee IAS officer Ganesh Koyu, who was to have visited China as part of a 100-member IAS delegation, led to cancellation of the visit of the entire delegation in protest.

China had cancelled visas of several Arunachalees, including ministers earlier too, as it claims entire Arunachal Pradesh as its territory and took the stance that indigenous inhabitants of Arunachal did not need visa to visit it.
