Sikkim government officials said the defence minister also made a survey of the new Pakyong Airport in East Sikkim and neighbouring areas this afternoon.
The survey follows the external affairs ministry statement yesterday that there were no new developments at the India-China military face-off site in Doklam and its vicinity since the August 28 disengagement.
The statement had come amidst reports that China has maintained a sizeable presence of its troops near the Doklam standoff site and even started widening an existing road around 12 km from the area of face-off.
Ms Sitharaman is scheduled to meet Sikkim Governor Sriniwas Patil and Chief Minister Pawan Chamling at the Raj Bhavan and they are likely to discuss several issues related to defence in the border areas with China, the officials today said.
Improving strategic infrastructure like border roads in Sikkim, the new airport which is to be inaugurated in November, and development in areas along the Sino-India border in Sikkim are likely to be discussed, they added.
