Since there were no provincial corporate city commercial banks in Gansu Province at the time, the Gansu Provincial People's Government decided to establish a provincial corporate city commercial bank based on Baiyin Commercial Bank and Pingliang Commercial Bank to promote economic development in Gansu Province. Therefore, on May 30, 2011, 25 legal entities (including large and medium-sized state-owned enterprises in Gansu Province and private enterprises within and outside Gansu Province), representatives of all shareholders of Baiyin Commercial Bank and representatives of all shareholders of Pingliang Commercial Bank jointly signed the “Dunhuang Bank Co., Ltd. Sponsor Agreement”. According to the agreement, 25 legal entities invested in currency, and all shareholders of Baiyin Commercial Bank and all shareholders of Pingliang Commercial Bank invested in the assessed net assets of Baiyin Commercial Bank and Pingliang Commercial Bank to jointly initiate the establishment of Dunhuang Bank Co., Ltd. On August 24, 2011, the General Office of the Gansu Provincial People's Government approved changing the name of the proposed bank from “Dunhuang Bank Co., Ltd.” to “Bank of Gansu Co., Ltd.” On 2011/9/27, the former China Banking Insurance Regulatory Commission approved the Bank's preparations. On November 18, 2011, the Gansu Regulatory Bureau of the former China Banking Insurance Regulatory Commission approved the opening of the Bank and agreed to change Baiyin Commercial Bank, Pingliang Commercial Bank and their branches to Baiyin Branch, Pingliang Branch and their branches respectively. On the same day, the Bank was issued a corporate legal entity business license issued by the Gansu Provincial Administration for Industry and Commerce, and the Bank was formally established in accordance with the “China Company Law”. This is a provincial corporate city commercial bank in Gansu Province. The Bank's H shares have been listed on the main board of the Hong Kong Stock Exchange since January 18, 2018. Since the Bank was established in China, the Bank's corporate structure and articles of association are governed by relevant Chinese laws and regulations. The Bank conducts banking business in China under the supervision and regulation of the General Financial Supervisory Authority and the People's Bank of China. The Bank is not an authorized institution as defined in the Banking Ordinance, is not subject to supervision by the Hong Kong Monetary Authority, and is not permitted to conduct banking and/or deposit acceptance business in Hong Kong.
