HONG KONG (Reuters) - Chinese sportswear group Li Ning Co Ltd said on Thursday it planned to sell HK$10.5 billion ($1.35 billion) worth of new shares to raise capital for international expansion and for investment in newly launched product categories. The Beijing-based company plans to sell 120 million new shares, or 4.59% of the enlarged share capital, to its major shareholder Viva China Holdings Ltd, it said in a filing to the Hong Kong bourse. The new shares will be issued at HK$87.50 apiece, or a 8.09% discount to Wednesday’s close, with proceeds also to be used for investment in re-engineered infrastructure and supply chain systems, for brand building and working capital. Viva will buy the new shares on completion of the sale of the same amount of existing shares at the same price to third-party investors. Its stake in Li Ning will be diluted to 10.37% from 10.87% after the deal. ($1 = 7.7779 Hong Kong dollars) Reporting by Donny Kwok; Editing by Christian Schmollinger
