Et-China.com International Holdings, an online travel service company based in South China's Guangdong Province, will float shares on AIM, London's second board, on July 31 and aims to raise 42 million pounds, sources said.

The flotation will make Et-China the third Chinese travel operator publicly traded overseas, following Ctrip.com International Ltd and eLong Inc, which are already listed on NASDAQ.

Et-China previously aimed to raise 12.5 million pounds. It has now set the price at 1.27 pounds per share and upgraded the expected proceeds to 42 million pounds.
