Connectivity stands out as one key theme of Xi's vision for Asia-Pacific development. He once invoked a concept from traditional Chinese medicine to illustrate APEC cooperation: when there is free flow, there is no pain; when there is pain, there is no free flow. "Connectivity makes the economic arteries of the Asia-Pacific flow more smoothly," he explained.

During his 2013 trip to Indonesia, Xi proposed the 21st Century Maritime Silk Road, a pivotal component of the Belt and Road Initiative (BRI), and proposed plans for establishing the Asian Infrastructure Investment Bank to support the BRI.

To date, more than half of APEC's 21 economies have engaged in Belt and Road cooperation, with signature projects like the Jakarta-Bandung High-Speed Railway in Indonesia and Chancay Port in Peru aiming to help strengthen trade networks and drive growth across the region.

"President Xi has put forward a series of proposals and initiatives to enhance Asia-Pacific regional cooperation, and the BRI is a major one to promote regional comprehensive connectivity," said Liu Chenyang, director of the APEC study center at Tianjin-based Nankai University.

"These efforts led by President Xi have also shown the world China's determination to take root in the Asia-Pacific and benefit the region in the long run," Liu said.
