India has given China evidence — on several occasions — of its involvement in aiding insurgency movements in India’s northeast, government officials have told HT. “There was evidence that insurgents from India’s northeast were meeting Chinese intelligence officials regularly in Yunnan (China) and in Nepal. We tracked top NSCN (National Socialist Council of Nagaland) arms procurer Anthony Shimray who had ordered a massive supply of weapons. The procedures involved in shipment, export orders, regulatory compliances, etc are impossible without China’s involvement,” said GK Pillay, former home secretary.
