SHANGHAI, Sept. 11 (Xinhua) -- China has launched its first domestically built polar research vessel and icebreaker "Xuelong 2" or "Snow Dragon" which will be operational in the first half of 2019.

The vessel was deployed in Shanghai on Monday and will go through a series of tests and interior decoration before beginning official operations, according to its builder Jiangnan Shipyard Group.
