He added that during the field visits, he had collected contacts from several Chinese companies.

"As a start, we would like to initiate memoranda of understanding between Chinese enterprises and their sister enterprises in The Gambia to chart a pathway for possible cooperation and collaboration in the future," Marong said.

Ethiopian engineer Ebsa Tesfa Hordofa, 33, also saw the seminar as a valuable opportunity to learn from China's experience.

"China has emerged as a global leader in the field of new energy, demonstrating remarkable progress with deployment, integration and innovation of renewable energy technologies," he said.

One particular visit resonated deeply with him — at a technical college in Baoding.

"I was especially struck by how theoretical concepts were brought to life through real hands-on laboratory setups," he said, adding that the simulations and the use of virtual reality in laboratories made the visit unforgettable.

He added that the students found the wind power operation, the simulation lab and the power cable distribution room exceptional. "It reflects China's strong commitment to preparing the next generation and maintaining an efficient and secure power system," Hordofa said.

Most importantly, he added, the experience has enhanced his technical skills and global outlook, enabling him to drive energy modernization and support sustainable development in his own country.

According to Hordofa, a critical challenge for his country is its heavy dependence on hydropower — over 90 percent — making the power system vulnerable to drought and environmental sustainability.

During the field visits, he found the modern, digital power system relay protection systems and battery storage systems amazing.

"These technologies that can enhance grid stability, support renewable integration and improve fault detection and system reliability can be directly applicable to my country," Hordofa said.
