The Bank of Tokyo-Mitsubishi UFJ is in negotiations with Bank of China with a view to becoming the fourth direct foreign investor in the country’s second-largest commercial lender, according to a report in Japan’s Yomiuri daily newspaper. Talks over the potential equity stake, which the paper said is likely to be signed by March, are believed to be being led by the newly formed banking unit of Mitsubishi UFJ Financial Group. The Japanese bank, the world’s largest by assets, plans to offer credit cards and other individual banking services to Chinese customers.
