Gangtok, May 2: The trade between Sikkim and Tibet through Nathu-la did not kick off today as customs officers from India failed to reach the spot because of mudslides along Jawaharlal Nehru Marg.

The slides blocked the road connecting Gangtok with Nathu-la at 9th Mile and 13th Mile yesterday afternoon, trapping some 112 vehicles carrying tourists from Chhangu Lake to Gangtok.
