by the NIIST, Trivandrum in 1998 and (iii) Fruit Processing Unit with technology developed by the CFTRI, Mysore (presently being set up). In 1952, Keishing was elected to the first Lok Sabha representing the Socialist Party. Through his second term in the Lok Sabha, he informed Nehru that he wanted to join the Indian National Congress and remained with the party until his death. He first entered Manipur State's Vidhan Sabha in 1972, winning Phungyar seat, and represented the seat for 30 years, winning the election 7 times. In 2002, he lost in the assembly polls. His son, Victor Keishing, reclaimed the seat a few years later. After his defeat in the state polls in 2002, Rishang Keishing moved to Delhi, representing the state in Rajya Sabha for two terms, 2002 to 2008, and 2008 and 2014. In 2007 he became the country's oldest parliamentarian. He retired from Rajya Sabha in 2014, at the age of 93. Keishing, along with D. Athuido, a former Member of the Legislative Assembly, was expelled from the Manipur Congress for six years in May 1968. This disciplinary action was taken against them for signing a memorandum to the Prime Minister of India which suggested that the Naga-inhabited areas of Manipur should be merged with Nagaland. In August 1972, he spearheaded an agreement between then United Naga Integration Council and the ruling Indian National Congress which recognised the vision of a Greater Nagalim, a region that would integrate Nagaland and the Naga-populated districts of Manipur under one administration.

In 2014, Keishing declared that he would not contest the Rajya Sabha elections after serving two consecutive terms. He said, "I am not interested to continue now."
