Southwest China's Chongqing Municipality will build 20 more five-star luxury liners in three years, expanding the fleet to 34 in an aim to boost tourism of the picturesque Three Gorges on the Yangtze River, an official said Wednesday.

"We'll turn the luxury liners into tourist attractions," said Tan Xiwei, vice mayor of Chongqing, who is in Beijing attending the annual session of the country's parliament, the National People's Congress, as a deputy.

Chongqing used to focus on the unique landscape and the huge dam of the Three Gorges for development of tourist products.

"Now we also expect tourists will come here for enjoyment on the liners, which are described as floating luxury hotels," said Tan.

There are currently 14 five-star luxury liners in operation in Chongqing.
