Because of its low-cost, highly educated and abundant labour, improved infrastructure, and foreign direct investment, China, a developing nation, has played a crucial role in enhancing global supply chains (SCs) in recent decades. However, the implementation of domestic and global SCs needs to be improved with new measures in China’s legal system. The Chinese government should remove current barriers to improve the trading climate. Even though various analysts have identified the same issue, there needs to be a more focused examination of laws on environmental protection, customs, and tax. As a result, I aim to explain the legal options that may be used to overcome some of the current legal barriers, and the role that the United Nations Commission on International Trade Law (UNCITRAL) plays in creating favourable legal rulings for China’s global SCs. Nonetheless, more is needed, and further legislation is needed to address several legal deficiencies. The goal of this article is to support increasing the Chinese government’s concern over the issues so that it can improve domestic and global SCs.
