Belgian art collectors Guy and Myriam Ullens will open a non-profit museum in Beijing next November to showcase Chinese contemporary art. Ullens, a 72-year-old baron and retired industrialist, would not say how much he is investing. He is selling 14 Turner watercolors at Sotheby's later today, valued at an estimated 10 to 15 million pounds ($20 million to $30 million), to provide "financial flexibility'' for his philanthropic goals. The center -- located in Beijing's 798 or Dashanzi Art District, the site of a onetime military-electronics complex -- will be spread over 6,500 square meters. Architects Jean-Michel Wilmotte of France and Ma Qingyun of China are revamping the former factory, while Jan Debbaut, Tate's former director of collections, is an artistic adviser on the project. "We don't want to be at all commercial," Ullens said at a presentation with his wife Myriam in a hospitality suite of Claridge's Hotel in London."We're not going to be selling anything, except in the store."Ullens has long been going to China to pursue his family's business interests. In the mid-1980s, he made seven or eight visits a year, and began acquiring works by artists who were suddenly freed of the obligation to produce works for propaganda, the army and the regime. Traveling Art After retiring in 2000, Ullens exhibited his Chinese art in Belgium and France, and inside Beijing's Forbidden City. He then decided to seek a place in China to house the collection. Today, the couple own 1,300 Chinese works, out of an overall collection of some 1,700 artworks, according to Myriam Ullens, who also runs child-related charities in Nepal and a cancer foundation in Belgium. Three exhibitions are already planned for the new center. The first is "85 New Wave: The Birth of Chinese Contemporary Art," which covers the period when artists "moved away from socialist realism and started to express themselves,"said Virginia Ibbott, the external-relations director for the Ullens Center for Contemporary Arts. That will be followed by a retrospective devoted to Paris- based artist Huang Yong Ping. The third exhibition, held during the Beijing Olympics in 2008, will feature works from the Ullens collection and special commissions.
