Is there a border between Thailand and China?

China and Thailand have no national boundaries.

Thailand is located in the south-central part of Indochina Peninsula in Asia, bordering the Gulf of Thailand (Pacific Ocean) in the southeast, the Andaman Sea (Indian Ocean) in the southwest, Myanmar in the west and northwest, Laos in the northeast and Cambodia in the southeast. Its territory extends southward along the crater isthmus to the Malay Peninsula, bordering Malaysia, and its narrow part lives between the Indian Ocean and the Pacific Ocean.

To say that China and Thailand are friendly neighbors probably means that the friendship between the Chinese and Thai people goes back to ancient times. Hundreds of years ago, many China people began to settle in Thailand and gradually became an important part of Thai society, such as Thaksin Shinawatra, an immigrant descendant from China.
