Key will pay a four-day visit to India from October 24-27.
External Affairs Ministry Spokesperson Vikas Swarup said India's bid for NSG membership is likely to figure in talks between the two prime ministers besides other issues.
In the June Plenary of NSG in Seoul, despite strong American support, China stonewalled India's bid to get entry into the group on the grounds that it was a not a signatory to the Nuclear Non-Proliferation Treaty.
Key will arrive in Mumbai on the evening of October 24 where he will deliver a key note address at an event organised by Bombay Stock Exchange in association with Chambers of Commerce.
