BEIJING - Waxworks company Madame Tussauds on Thursday launched its latest outpost in Beijing , with models of Chinese political leaders conspicuous by their absence. US President Barack Obama was on display, along with a grim-looking Vladimir Putin of Russia, and Britain’s Queen Elizabeth II. Even Karl Marx, founding father of Communism, was included. But there was no sign of Mao Zedong, Deng Xiaoping, or current Chinese President Xi Jinping, nor of a Chamber of Horrors, one of the most popular sections of the original attraction in London. Craig Dunkerley, Asia and Europe head of openings for Merlin Entertainments, the firm that owns Madame Tussauds , told AFP that it was ‘still in discussion’ with Chinese authorities over including domestic political figures.
