China's support is crucial for India as new membership in the Nuclear Suppliers Group is guided by the consensus principle.
"China's position on the non-NPT members' participation in the NSG has not changed," Chinese Foreign Ministry spokesperson Hua Chunying told a media briefing.
She was responding to a question about the chances of India's admission into the grouping during the next month's plenary session expected to take place in the Swiss capital, Bern.
"We support the NSG group following the mandate of the 2016 Seoul plenary session and following building consensus as well as inter-governmental process is open and transparent to deal with the relevant issue in a two-step approach," Hua said.
After India applied for membership in the NSG, Pakistan -- the all-weather ally of China -- also submitted its membership bid with Beijing's backing.
India is not a signatory to the NPT. India says it will not sign the NPT as it regards it discriminatory.
After a series of meetings between officials of India and China, Beijing backed a two-step approach which stipulates that the Nuclear Suppliers Group 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 the discussions on specific cases.
Analysts here say that with the bilateral discord between India and China increasing, especially after India's boycott of last week's Belt and Road Forum (BRF), China's stand on India's admission into the NSG as well as on the UN listing of JeM leader Masood Azhar will be further hardened.
China's Belt and Road (BR) initiative is being opposed by India as it includes the USD 50 billion China Pakistan Economic Corridor (CPEC) which traverses through Pakistan-occupied Kashmir.
