Legal basis: Article 4 of the Interim Regulations on the Administration of Banks in People's Republic of China (PRC) prohibits non-financial institutions from engaging in financial business, while lending belongs to financial business, so enterprises of non-financial institutions are not allowed to lend to each other. Lending activities between enterprises can not only prosper China's market economy, but also disrupt the normal financial order, interfere with the implementation of national credit policies and plans, weaken the state's monitoring of investment scale, and cause chaos in the economic order.
