Three red lines
The three red lines (Chinese: 三條紅線, Simplified: 三条红线, Pinyin: sān tiáo hóng xiàn) are financial regulatory guidelines in the People's Republic of China introduced in August 2020 relating to the ratio of debt to cash, equity, and assets. It was introduced to help rein in the highly indebted property-development sector in China, seen especially in large real estate concerns such as Evergrande, which faced a liquidity crisis in Q4 2021.
