Which one among the following countries of Asia is land-locked ?

Laos is the only landlocked country in Southeast Asia [1]. It is situated on the Indochina Peninsula and is bordered by China to the north, Vietnam to the east, Cambodia to the south, Thailand to the west, and Myanmar to the northwest [1]. Unlike its neighbors, Laos lacks direct access to the sea, which necessitates the transit of its exports and imports through neighboring countries to reach maritime ports. In contrast, Vietnam possesses an extensive coastline along the South China Sea, Cambodia borders the Gulf of Thailand, and Thailand has significant coastlines along both the Andaman Sea and the Gulf of Thailand. The Mekong River serves as a vital geographical feature for Laos, forming much of its western border with Thailand and supporting its agrarian economy despite its landlocked status.
