The decision was made on Thursday, when the majority of the 17-strong committee said "yes" to the Chinese submarines, saying that it was the "best value for money". Other committee members remained split between offers from South Korea and Germany.
According to the source, the committee voted to buy the Chinese submarines because they are "equipped with superior weaponry and technology and are also able to stay underwater longer."
In July 2014, the Royal Thai Navy inaugurated a state-of-the-art submarine squadron headquarters and training center for this squadron, even though the navy has had no submarines in its fleet since 1951.
The squadron's facilities, which include a German submarine simulator, were established at an existing naval base in Sattahip, east of Bangkok in the Gulf of Thailand.
Earlier, the Thai government allocated almost 6 million dollars for the navy dealing with the feasibility of purchasing submarines from Germany, South Korea or China.
