"This is an example and reflection of Russia's unwavering support to India's membership of global export control regimes", Ryabkov told journalists.
The plenary session of the group members is set on Thursday.
Russia, France, Germany and the United States are strongly supporting India's entry into the Wassenaar Arrangement, which controls the global trade of conventional weapons and dual-use goods and technologies.
Russia's Deputy Foreign Minister Sergei Ryabkov, who was in India for the foreign office consultations, described India's non-proliferation record as "impeccable".
Reacting to his statement, the Chinese foreign ministry said Beijing won't change its mind on India's entry.
India already enjoys most of the benefits of membership under a 2008 exemption to NSG rules granted to support its nuclear cooperation deal with Washington. "In this circumstance if we agree for the above-mentioned applications, it will have two consequences, that is to recognise the nuclear weapons status of the Non-NPT countries".
"On this we will further discuss application of non-contracting parties", Geng said.
"The third article of NPT says that the nuclear weapon free countries must sign CSA".
China suggested that the NSG can pool the wisdom and further explore on this issue and find a solution which can be accepted by all relevant parties and can uphold the worldwide non-proliferation regime with NPT as a cornerstone.
"We recognise that at the moment there is no unanimity on Pakistan's application and that the same can not be interlinked with India's", said Ryabkov, after his meeting with Jaishankar. At the same time they will exchange views on global issues of common concern.
