"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 currently 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.
China's repeated stonewalling of India's membership bid in the NSG has become a major stumbling block in bilateral relations.
