This is also the first batch of pilgrims though the Nathu-La route after the pilgrimage was stopped following the Dokalam standoff last year. India and China had agreed in April to resume the Kailash Mansarovar Yatra through the route.
Minister of State for External Affairs V K Singh had in a written reply to a question in the Lok Sabha had said the yatra for 2018 though Nathu-La would take place between June and September.
The special secretary to tourism and civil aviation department, Namrata Thapa and some other officials were present at Nathu-La during the crossing over of the yatris to China, an information and public relations department release said.
Earlier, the yatris had spent two days at 15th mile at Sherathang in Sikkim for acclimatization.
The route via Nathu-La is in addition to the older route via Lipulekh Pass in Uttarakhand, the only route earlier that was badly damaged in the 2013 floods. Both the routes are operational but the new route via Nathu-La is shorter, safer and more comfortable.
The yatra via Nathu-La began in 2015.
