China is expected to see 171.76 million cross-regional passenger trips on Wednesday, the 38th day of its annual Spring Festival travel rush, according to the country's Ministry of Transport.
The figure marked a 1.7-percent decrease from the previous day but a 0.6-percent increase from the same period in 2025.
China's railway system expects to handle an estimated passenger volume of 9.1 million trips, down 2.9 percent from the previous day and 11.5 percent from the same period in 2025.
The passenger flows on roads are set to reach an estimated 159.96 million trips, down 1.6 percent from the previous day but up 1.4 percent from the same period of last year.
Waterway passenger volume is expected to hit an estimated 630,000 trips, down 1.5 percent from the previous day and up 11.1 percent from the same period in 2025.
The civil aviation sector expects to handle 2.07 million passenger trips, up 0.8 percent from the previous day but down 1.7 percent from the corresponding period of the year before.
Cross-regional passenger flow lowers as Spring Festival travel rush nears end
China's first 500-kV cross-border alternating-current power interconnection project entered service Monday, creating the highest voltage grid tie between the two countries and advancing Belt and Road energy cooperation.
The project raises two-way power transfer capacity between the two countries from 50,000 kW to 1.5 million kW, enabling the annual transmission of about 3 billion kWh of clean electricity, roughly 30 times the capacity of previous lines, according to China Southern Power Grid.
As the largest cross-border grid project and the highest-voltage power link between China and Laos, it connects southwest China's Yunnan Province with Oudomxay and Luang Namtha provinces in northern Laos.
Cross-border electricity trading began as the project entered operation. About 4.81 million kWh of power from clean energy bases in northern Laos was transmitted to Yunnan through the new line, marking a more regular and institutionalized phase of power connectivity between the two countries.
It is also the first time an overseas new energy project has participated in China's electricity market, the company said. The power involved in the transaction came from a large mountain photovoltaic project in Laos, one of the core supporting power sources for the interconnection line.
"This project is the cross-border power grid project with the highest voltage level between China and Laos. Leveraging the China-Laos power grid interconnection and the power markets in southern China, surplus hydropower from Laos can be transmitted to China during the rainy season, while China can supply supplemental power to northern Laos during the dry season. This project represents yet another landmark achievement between China and Laos in deepening power cooperation and jointly advancing the high-quality development of the Belt and Road Initiative," said Li Jingru, general manager of Electricite du Laos Transmission Company Limited (EDL-T), a joint venture of China Southern Power Grid and Lao state-run Electricite du Laos.
The solar project has an average annual power generation capacity of about 1.65 billion kWh. In 2026, it is expected to transmit about 1.1 billion kWh of solar power across the border, supporting energy complementarity between the two countries.
"In the future, efforts will be made to further promote normalized cross-border electricity trading, meet the trading needs such as electricity transmission from Laos to China's Yunnan, from China's Yunnan to Laos, and from Laos to China's Guangdong, and facilitate the optimal allocation of energy resources in the Lancang-Mekong region," said Li Minhong, marketing director of China Southern Power Grid.
Construction of the interconnection project began in late February last year. Spanning a total length of 177.5 km, the transmission line includes a 145-km Chinese section and a 32.5-km Lao section.
