Bhutan's King Jigme Khesar Namgyel Wangchuck unveiled plans for a mega city project near the Indian border - the Gelephu Special Administration Region (SAR), spreading across 1,000 sq km. The project will link Bhutan economically with Assam to spur regional and sub-regional integration. The project will be part of the Sarpang district special economic zone and include an international airport at Gelephu. India and Bhutan are also planning to put in place a 58-km rail link between Gelephu and Kokrajhar in Assam.
