A bulk of the troops of the Sukna-based 33 Corps have been or are in the process of being moved to the Indo-China frontier in Sikkim even as the controversy over the Doklam plateau at the India-Bhutan-China tri-junction continues to surface from time to time.

Eastern Command army sources revealed that all three divisions under the 33 Corps, which is stationed in Sukna, near Siliguri in West Bengal, have been deployed on the Sino-Indian border.

The troop movement from Sukna began about 20-25 days ago. The most important and vital elements of the corps have moved up and taken position in designated "Op Areas".
