"As for non-NPT counties being admitted to the group, I can tell you there is no change to China's position," Foreign Ministry spokesman Geng Shuang told a media briefing.
He was replying to a question whether there is any change in China's stand at the plenary meeting taking place in the Swiss capital, Bern.
"I want to point out that the NSG has clear rules on admission of new members and the Seoul plenary made clear mandates on how to deal with this issue. With these rules and mandates, we need to act as they dictate," he said.
"As for the criteria regarding admitting new members, as far as I know this plenary meeting in Switzerland will follow mandate of the Seoul plenary and uphold principle of decision upon consensus and continue to discuss various dimensions like technology, law, legal and political aspects of non-NPT countries admission the group," he said.
China's stand, stonewalling India's admission, has become a major stumbling block in bilateral relations between the two countries.
While India, which is backed by the US and a number of western countries has garnered the support of a majority of the group's members, China has stuck to its stand that new members should sign the Nuclear Non-Proliferation Treaty (NPT), making India's entry difficult as the group is guided by the consensus principle.
India is not a signatory to the NPT.
After a series of meetings, China has backed a two-step approach which stipulates that the NSG members first need to arrive at a set of principles for the admission of non-NPT states into the NSG and then move forward with discussions of specific cases.
The Bern meeting is being regarded significant as it is taking place after Russian President Vladimir Putin reportedly took up the issue of India's accession to NSG with his Chinese counterpart Xi Jinping during their recent meeting at Astana on the sidelines of the Shanghai Cooperation Organisation (SCO) summit.
