CITIC Petroleum and Pearl River Rong Zhen are both oil companies, but Pearl River Rong Zhen has more advantages in business scope and market position. Pearl River Rong Zhen is a leading manufacturer of petroleum equipment in China, with rich technology and experience. Its products cover many fields such as oil exploration, oil production, oil transportation and oil storage. At the same time, the Pearl River Rong Zhen also has a wide range of customers and markets at home and abroad, with high visibility and influence. In contrast, CITIC Petroleum's business scope and market position are relatively weak. Therefore, on the whole, the Pearl River Rong Zhen is better.
