Due to the policy restrictions of various countries and regions and the differences in local economic development and openness, Citibank's overseas development in the Asia-Pacific region is quite different. Traditionally, most countries restrict access to financial markets, while others restrict actual business activities after entering the market. Nevertheless, it seems that the decision-makers of Citigroup have never given up their efforts to expand their business in this region. One of their main strategies is the market preemptive strategy, that is, once there is an opportunity, they will enter the market before other competitors and expand their business rapidly.

For example, in Korea, Malaysia, Vietnam and other countries, Citibank was the first to enter. Pre-emptive strategy can not only quickly occupy the market and expand the influence of enterprises, but also actively set up operating institutions to expand business areas and create entry barriers for latecomers, thus ensuring competitive advantage.

For different countries at different stages of development, Citibank's market development strategy is also different. For an underdeveloped region like Vietnam, its main business direction is to provide cash management, short-term financing and foreign exchange trading services for American multinational companies and local enterprises (in Vietnam, any enterprise must set up local currency accounts and US dollar accounts in two different banks); For countries such as India, provide syndicated loans, project financing, bonds and retail business; In countries with rapid economic development, such as Malaysia and Singapore, they provide more complex services, such as securities business and financial derivatives. As for a mature country like Japan, Citibank provides more comprehensive services, including banking, trust, securities, leasing and futures.
