The relationship between Sri Lanka and India is Sri Lanka a part of India?

Sri Lanka is an independent sovereign country and has nothing to do with India.

Sri Lanka, the full name of the Democratic Socialist Republic of Sri Lanka, formerly known as Ceylon, is a tropical island country located in the Indian Ocean and a member of the Commonwealth. In ancient China, it was called Lion Country, Lion Country and Sinhalese Country. Sri Lanka's economy is dominated by agriculture, and the country's most important export product is Ceylon black tea. The country is also one of the four largest tea-producing countries in the world, so the domestic economy is deeply influenced by tea production. In the process of liberalization, the growth rate continues to accelerate. The biggest advantage of Sri Lanka lies in its mining industry and geographical location. It is a gem-rich island, the world's top five gem producing areas, and is known as the "gem island". Therefore, in the initial stage of the economy, the mining industry has given it many advantages in its initial development. The export value of precious stones can reach 500 million dollars every year, among which rubies, sapphires and cat's eyes are the most famous. Sri Lanka, which means "promised land" or "bright and rich land" in Sinhalese, has the reputation of "the jewel kingdom" and "the pearl in the Indian Ocean" and is considered as the most beautiful island by Kelpolo. Sri Lanka has been involved in international affairs for a long time. It is a founding member of the South Asian Association for Regional Cooperation and a member of the United Nations, the Commonwealth, the Group of 77 and the Non-Aligned Movement. It is the only human development index in South Asian countries that is rated as "high" at present.
