Tencent has offered to buy all stakes of domestic online travel firm Elong, offering 18 US dollars per share.

The proposed purchase price is a 27% premium to Monday's closing price.

So far, no agreement has yet been reached.

This would be Elong's first step in going private and delisting from the New York Stock Exchanges.

Apart from Tencent, other investors of Elong include online travel giant Ctrip and Keystone Lodging Holdings.

Earlier, Ctrip went on record saying it will team up with Tencent in the proposed takeover deal.
