India–South Korea relations

India–South Korea relations are the bilateral relations between India and South Korea. Formal establishment of diplomatic ties between the two countries occurred in 1973. Since then, several trade agreements have been reached, such as the Agreement on Trade Promotion and Economic and Technological Co-operation in 1974, the Agreement on Co-operation in Science & Technology in 1976, the Convention on Double Taxation Avoidance in 1985, and the Bilateral Investment Promotion/Protection Agreement in 1996.

Trade between the two nations has increased greatly, from $530 million during the fiscal year of 1992–1993, to billion during 2006–2007. It further increased to US$17.6 billion in the year 2013.

India–South Korea relations have made great strides in recent years and have become truly multidimensional, spurred by a significant convergence of interests, mutual goodwill and high-level exchanges. South Korea is currently the fifth largest source of investment in India. Korean companies such as LG, Samsung and Hyundai have established manufacturing and service facilities in India, and several Korean construction companies won grants for a portion of the many infrastructural building plans in India, such as the National Highways Development Project. Tata Motors' purchase of Daewoo Commercial Vehicles at the cost of US$102 million highlights India's investments in Korea, which consist mostly of subcontracting.

The Indian Community in Korea is estimated to number 8,000. Their composition includes businesspeople, IT professionals, scientists, research fellows, students and workers. There are about 150 businesspeople dealing mainly in textiles. Over 1,000 IT professionals and software engineers have recently come to Korea to work, including in large conglomerates such as Samsung and LG. There are about 500 scientists and post-doctoral research scholars in Korea.

Indian diamond drilled carnelian beads have been discovered in Korea dating back to proto three kingdoms period (100–669 AD).

Buddhism in Korea
Centuries after Buddhism originated in India, Mahayana Buddhism arrived in China through the Silk Route in the 1st century CE via Tibet, then to the Korean peninsula in the 3rd century during the Three Kingdoms period from where it transmitted to Japan. The Samguk yusa records the following three monks as being among the first to bring Buddhist teaching, or Dharma, to Korea: Malananta (late 4th century), an Indian Buddhist monk who brought Buddhism to Baekje in the southern Korean peninsula; Sundo, a Chinese Buddhist monk who brought Buddhism to Goguryeo in northern Korea; and Ado, a Chinese Buddhist monk who brought Buddhism to Silla in central Korea. In Korea, it was adopted as the state religion of three constituent polities of the Three Kingdoms period, first by the Goguryeo (Gaya) in 372 CE, by the Silla in 528 CE, and by the Baekje in 552 CE.

In 526 CE, Korea monk Gyeomik went to India to learn Sanskrit and study the monastic discipline Vinaya, and founded the Gyeyul branch of Buddhism that specializes in the study of Vinaya which derives directly from the Indian Vinaya School.

A 2005 government survey indicated that about a quarter of South Koreans identified as Buddhist, though including the people outside of the practicing population who are deeply influenced by Buddhism as part of Korean traditions, the number of Buddhists in South Korea is considered to be much larger. Similarly, in officially atheist North Korea, while Buddhists officially account for 4.5% of the population, a much larger number (over 70%) of the population are influenced by Buddhist philosophies and customs.

The fact that people on the Indian subcontinent were familiar with Korea's customs and beliefs is amply testified by the records of the Chinese Buddhist pilgrim Yijing, who reached India in 673. Yijing writes that Indians regarded Koreans as "worshipers of the rooster". This concept about Koreans was grounded in a legend of the Silla dynasty.

In 2001, a memorial of Heo Hwang-ok from 48 C.E., who is believed to be a princess of Indian origin named Suriratna, was inaugurated by a Korean delegation in the city of Ayodhya, India, which included over a hundred historians and government representatives. In 2016, a Korean delegation proposed to develop the memorial. The proposal was accepted by the Uttar Pradesh chief minister Akhilesh Yadav. Kim Jung-sook, first lady of South Korea, inaugurated the groundbreaking of the Queen Heo Hwang-ok memorial with chief minister of Uttar Pradesh Yogi Adityanath in November 2018, which was planned to be completed in 2020. Gimhae, which already has a tomb and pagoda of Queen Heo Hwang-ok, is now constructing 3000 square meters of museum and exhibition hall.

A famous Korean visitor to India was Hyecho, a Korean Buddhist monk from Silla, one of the three Korean kingdoms of the period. On the advice of his Indian teachers in China, he set out for India in 723 CE to acquaint himself with the language and culture of the land of the Buddha. He wrote a travelogue of his journey in Chinese, Wang ocheonchukguk jeon or "An account of travel to the five Indian kingdoms". The work was long thought to be lost. However, a manuscript turned up among the Dunhuang manuscripts during the early 20th century.

A rich merchant from the Ma'bar Sultanate, Abu Ali (P'aehali) 孛哈里 (or 布哈爾 Buhaer), was associated closely with the Ma'bar royal family. After falling out with them, he moved to Yuan dynasty China, married a Korean woman and received a job from the Mongol emperor. His wife was formerly married to Sangha, a Tibetan, and her father was Ch'ae In'gyu during the reign of Chungnyeol of Goryeo, recorded in the Dongguk Tonggam, Goryeosa and Liu Mengyan's Zhong'anji.
