What are the problems in the outsourcing of Coca-Cola Company?

Take my own company as an example:

The core business of Beijing Oriental Frontier Information Consulting Co., Ltd. is to provide a platform for domestic enterprises to explore the international market, and help domestic enterprises to enter foreign markets with the help of foreign exhibitions, foreign media, foreign importer databases and foreign product customs databases. Non-core business is the external reception for enterprises to go abroad to participate in exhibitions. This business is outsourced to foreign travel agencies. On the one hand, it reduces our manpower and time investment, and does not need to spend a lot of time and energy to implement various reception arrangements abroad. On the other hand, it reduces the intermediate links of travel agencies in China (the general practice of tour groups is to find travel agencies at home and travel agencies at home to find foreign travel agencies, which increases the cost of enterprises abroad).
