Russia's Gazprom is planning to list on Singapore's stock exchange in July, Interfax agency quoted a company source as saying Thursday.
Interfax reported that state-controlled Gazprom, the country's top natural gas producer, was talking to the exchange and preparing paperwork.
Gazprom, which is negotiating a deal to supply natural gas to China, declined to comment.
President Vladimir Putin hoped the negotiations will be concluded before he visits China next week, showing Moscow had alternative markets to turn to at a time of tension with the West over the crisis in Ukraine.
Russia and China are still trying to iron out price differences over the potential deal.
