India and Indonesia or Indo-indonesian relations established diplomatic relations in 1951. Both countries are neighbours, as India's Andaman and Nicobar Islands share a maritime border with Indonesia along the Andaman Sea. The Indian-Indonesian relationship stretches back for almost two millennia. In 1950, the first President of Indonesia, Sukarno, called upon the peoples of Indonesia and India to "intensify the cordial relations" that had existed between the two countries "for more than 1000 years" before they had been "disrupted" by colonial powers.
