India's southern neighbour Sri Lanka is witnessing a controversy after some Chinese men in military fatigues were reportedly spotted dredging an ancient tank in Hambantota. While the Rajapaksa government ruling the island nation has tried to dismiss concerns, Opposition parties have questioned why China is being allowed to break laws regarding the wearing of military uniforms. The concern is not limited to Lanka. Should India be worrying about another of its neighbours going the Pakistan way, with Beijing acting as a neo-coloniser and surrounding India with its vassals? Hindustan Times senior editor Aditi Prasad discusses the situation, and India's possible response, with former diplomat Phunchok Stobdan.
