Under what circumstances can a company reinvest and become a joint and several liability?

A company may invest in other enterprises, but it shall not be jointly and severally liable for the debts of the invested enterprises unless otherwise provided by law. Explain that the company can't invest in the partnership, because the partnership requires the partners to bear unlimited joint liability. If the company is jointly and severally liable for the debts of the partnership due to foreign investment, it will undoubtedly increase the company's operating risks and actually harm the interests of shareholders and creditors. For example, if A and B set up a limited liability company and A invests in other entities to set up a general partnership, A will bear unlimited joint liability, which is not in line with the regulations. However, Company A can invest as a limited partner to establish a limited partnership.
