Australia and New Zealand Banking Group, Australia's third-largest lender, plans to invest A$300 million ($388.4 million) to expand its branch network and increase lending in China.
ANZ was the first Australian bank to invest in China and has six outlets in Beijing, Shanghai, Chongqing and Guangzhou.
It plans to increase its network to 20 outlets over the next 10 years, subject to regulatory approval.
The capital follows an initial investment of A$395 million.
"The additional capital we plan to invest in ANZ China will support further network expansion, growth in customer lending, employee recruitment and product development to better service our customers," chief executive Mike Smith said. "We have a long-term commitment to China and will continue to be an active investor in supporting the nation's financial services sector."
The bank said its aim was to become a "super-regional bank" in the Asia Pacific region. By 2017 it hopes 25 per cent to 30 per cent of group profit will come from outside New Zealand and Australia.
ANZ also has a 20 per cent stake in Shanghai Rural Commercial Bank and Bank of Tianjin.
It wholly owns a rural bank in Liangping county, the Chingqing Liangping ANZ Rural Bank.
