Along the banks of the Mekong River in Vientiane, the capital of Laos, stands a recently expanded modern medical complex — Mahosot Hospital, Laos' first hospital when established in 1910 and now its largest.

Financed by Chinese funds and with a total investment of about $92 million, the expanded hospital now spans three hectares, with 600 beds and a rooftop helicopter pad.

In 2017, President Xi Jinping made a state visit to Laos — the first by a Chinese head of state and top leader of the Communist Party of China in 11 years.

Since then, there have been frequent mutual visits between Chinese and Lao leaders. In the latest development, General Secretary of the Lao People's Revolutionary Party Central Committee and Lao President Thongloun Sisoulith arrived on Tuesday in Hangzhou, the capital of eastern China's Zhejiang province, formally starting a five-day state visit.
