Raising the issue during the Zero Hour in Rajya Sabha, V Maitreyan said 1.5 lakh Tamils were killed in the "planned and systematic genocide" but so far no reliable investigation has taken place and not a single guilty has been punished.
He said the session of the UNHRC is in progress in Geneva and the resolution will be put to vote on March 22.
"It is really shocking to Tamils the world over that the US, UK and other countries have sponsored resolution in the UNHRC deciding to give two more years until 2019 for Lanka to submit its report (regarding the genocide)," Maitreyan said.
He further said a new provision has been added to the resolution which states that only with the permission of the Lankan government, foreign jurists or lawyers can enter the country.
The AIADMK member said former Chief Minister of Tamil Nadu J Jayalalithaa, in her last memorandum to Prime Minister Narendra Modi, had urged the Centre to take necessary measures to bring to book those in Sri Lanka who were responsible for the genocide of Tamils and India should take initiative in this regard in the UNHRC.
"Prime Minister Narendra Modi is the most powerful leader in the country. In fact, he is the most powerful world leader. If Modi cannot render justice to Tamils, nobody else on the earth can do so," he said.
Maitreyan asked the government to oppose the resolution in the UNHRC on March 22.
