Bank of China Ltd. (3988.HK) wants to take part in the financing of Aluminum Corp. of China's US$19.5 billion purchase of Rio Tinto PLC (RTP) assets, the official Xinhua News Agency reported late Friday, citing bank Chairman Xiao Gang.

Xiao also said Temasek Holdings Pte. Ltd. has pledged not to sell its holding in Bank of China at least in the first half of this year, according to the report.

He said his bank isn't interested in taking part in HSBC Holdings PLC's (HBC) rights issue, nor will it bid for American International Group Inc.'s (AIG) Asian assets.
