In addition to the "dowry," Chao has also pledged to help the successful suitor launch his own business. He called the prize money "an inducement to attract someone who has the talent, but not the capital, to start his own business," according to CTV News [id.].
No news about whether or not prospective suitors have come forward, but it seems unlikely Gigi would be interested. The 33-year-old, who graduated from the University of Manchester and now works as a director at her father's company, was in a seven-year-long relationship with her new wife before they tied the knot in France.
The BBC reports [ http://www.bbc.co.uk/news/world-asia-19733003 ] that Gigi called her father's plan "entertaining," and has said she won't worry about it until a suitor has been found.
