Explanation :

Sri Lanka announced a one-year moratorium on foreign research vessels entering its waters, with the official reason being capacity building. The decision is being seen as a response to concerns raised by India regarding the stoppage of Chinese research vessels in the area. Foreign Ministry spokesperson Niluka Kadurugamuwa said the moratorium applies to all countries and is aimed at allowing local researchers to build capacity for joint research. This context includes growing geopolitical dynamics in the region, including strategic concerns and diplomatic engagements in the Indian Ocean region, particularly with China's efforts to expand its influence in Sri Lanka, located on one of the world's busiest shipping routes. The ban has been imposed amid the backdrop of moves.
