Three shipping industry figures have been caught up in China's latest political purge, including billionaire Wang Wenliang, the controversial chairman of Dandong Port Group.

This week China's National People's Congress (NPC), threw out 45 of its 2,987 delegates over allegations that they had bribed their way into the rubber-stamp legislature.

Shanghai shipping news website found three important shipping names among those on the official list published by state news agency Xinhua.
