CIMC Tonghua and CIMC Dongyue are both leading manufacturers of shipbuilding and marine engineering equipment in China, but CIMC Tonghua is more prominent in product research and development and technological innovation, with more patented technologies and independent research and development products, especially in the field of container terminal automation. At the same time, CIMC Tonghua has a broader market and customer base in the world and has a stronger international influence. In contrast, CIMC Dongyue is also excellent in product quality and service, but relatively weak in technological innovation and market expansion. Therefore, considering comprehensively, CIMC Tonghua is better.
