The job content of overseas banks is very different from that of domestic banks. The main strategy of overseas banks is to serve Chinese enterprises to go abroad. At present, most of their business is corporate business. According to the relationship with domestic banks, we can branch linkage business and localization business. Common businesses include trade financing, domestic insurance and foreign loans, syndicated loans, etc. Others include financial market business, intermediary business and so on. At present, the business of most overseas institutions is not complicated. The main reason is that there are no people and no resources. In fact, different countries, different institutions, at different stages, the work content is still very different. For example, the Karachi branch of ICBC has a respondent. If the system connection is not good, it is estimated that the business development is still relatively restricted. However, due to the close relationship between China and Pakistan, the future opportunities should be far greater than most European institutions.
