Nina Wang Kung Yu-sum hoped to win a Nobel Peace Prize for trying to broker talks between the Dalai Lama and Beijing, a court hearing rival claims to her multibillion-dollar estate was told yesterday. A senior executive at Wang's Chinachem Group said the late tycoon had her heart set on winning an award that would put her in the company of figures such as Nelson Mandela and Mother Teresa. But Heng Kim Thiam, Chinachem Group's head of project management and construction, said he was not sure if his boss had any luck in bringing Tibet's exiled spiritual leader and Beijing to the bargaining table. 'She hoped that she would receive a recommendation for the Nobel Peace Prize,' he told the Court of First Instance. 'To my recollection, she was trying to make a connection between the two parties.' Mr Heng was the first witness at the hearing to determine whether Wang's Chinachem Charitable Foundation or fung shui master Tony Chan Chun-chuen should inherit her estimated HK$100 billion fortune. Wang was an energetic and considerate woman who was 'full of ideas', Mr Heng said. But she was also known for her pie-in-the-sky suggestions and sometimes changed business plans at the last minute, he said under cross-examination by Jonathan Harris SC for Mr Chan. Wang built Chinachem into an international property empire following the 1990 kidnapping of her husband and company founder, Teddy Wang Tei-huei. He has never been found. Wang increased her public profile after Teddy Wang's disappearance, the court heard. She donated money to the United Nations, bought city property to prove to Hongkongers and mainland officials that she believed in the city's post-handover future and established a scholarship at Harvard University, Mr Heng said. Mr Harris challenged claims that Wang was obsessed with charitable giving, which are central to Chinachem's argument that it should control her estate to fund good causes. Her gestures seemed like 'an attempt to ingratiate herself with mainland authorities', he said. Denis Chang SC, Chinachem's barrister, called the suggestion very offensive. Mr Heng said Wang was 'deeply moved' by a Beijing agricultural show in the late 1990s and had a 'strong wish' to increase contributions to the mainland's poor and to education and medical research. He confirmed that Wang signed a 2002 will that left her estate to Chinachem. Mr Chan says his will, from 2006, voids the charity's claim.
