India's ruling Congress party made little progress in fresh talks Friday with its communist allies with whom it is locked in a bitter row over a nuclear deal with the United States, its leaders said.
Foreign Minister Pranab Mukherjee described the talks as "cordial" and said the two sides will meet again on Tuesday.
"The meeting carried forward earlier discussions on the basis of inputs provided by the two sides, Mukherjee told reporters after the talks.
Ahead of the meeting, the Communist Party of India (Marxist) adopted a tough stand, threatening to withdraw support if the government went ahead with the accord.
"If they proceed, we have made it clear that we will no longer support the government," senior party leader Sitaram Yechury told reporters.
The government last month set up a 15-member committee headed by Mukherjee to review objections by its left-wing allies to the nuclear agreement.
The pact, if implemented, would allow energy-hungry India to buy civilian nuclear technology while possessing nuclear weapons, despite not having signed the Nuclear Non-Proliferation Treaty.
