It provides funding for enterprises to expand into Mainland China, economies covered by Free Trade Agreements, and Investment Agreements. The fund covers projects in brand development, upgrading and transformation, and expanding domestic sales. However, the application process is complex and time-consuming, with a success rate of only about 35%. It is important for businesses to understand the requirements, prepare appropriate documentation, and seek professional assistance when applying for the BUD Fund.
