The official launch of the ECECP was endorsed in the EU-China Leaders Summit Joint Communique, which was signed in April between China and the EU.
Experts attending the launch event said both the EU and China are pioneers in energy transition, and both are major global economies and major energy consumers.
The fostering of exchanges and experience could play a vital role in helping China's energy transition, they pointed out.
For instance, China could learn from Germany's experience with power sector reforms.
Wang Zhongying, director general of the National Development and Reform Commission's Energy Research Institute, said Germany has four power transmission companies and some 800 power distribution and power supply companies.
In China, two state grid companies do the entire job, Wang said.
