Aden's pro-separatist officials reject Saudi flight restrictions, partially halt airport operations

Yemen's transport ministry on Thursday rejected new Saudi-imposed flight restrictions, calling a requirement for planes to stop in Saudi Arabia for security inspections an "air blockade" that undermines national sovereignty.

Officials loyal to the secessionist Southern Transitional Council (STC) have refused to comply with the new protocols ordered by Yemen's Saudi-backed central government, and have partially halted operations in Aden International Airport, the country's primary gateway, a source within the Yemeni government told China's Xinhua News Agency.

The standoff is the latest sign of a deepening fracture within the coalition fighting the Houthi group. While the STC is technically part of Yemen's ruling Presidential Leadership Council (PLC), the group seeks independence for southern Yemen and is frequently at odds with the internationally recognized government.

Saudi Arabia recently ordered all international flights departing and entering Yemen to undergo security screenings at Jeddah Airport before continuing to their final destinations. While some of those restrictions were later eased, they remain in place for all flights traveling to and from the United Arab Emirates (UAE), which is allegedly the main backer of STC.

Government officials said the measures are intended to curb the movement of STC leaders between Yemen and the UAE, effectively cutting off external support for the secessionist movement.

Tensions between the factions escalated this week after the STC seized large swathes of the oil-rich Hadramout province and the eastern province of Al-Mahrah. Riyadh considers these areas a "red line" due to their proximity to the Saudi border and their concentration of Yemen's remaining energy reserves.

On Tuesday, a Saudi-led coalition airstrike targeted vehicles at the port of Mukalla in Hadramout. Saudi officials said the vehicles were intended for STC forces. Following the strike, PLC Chairman Rashad al-Alimi canceled a joint defense agreement with the UAE and ordered all Emirati forces to leave the country within 24 hours. The UAE confirmed Thursday it has begun withdrawing its remaining troops from Hadramout, citing safety concerns.

The STC commands significant control over Aden and other southern cities. Several cabinet members, including Transport Minister Abdulsalam Saleh Humaid, are loyal to the STC rather than the central leadership.

China's two major power grid operators -- the State Grid Corporation of China (State Grid) and China Southern Power Grid (CSG) -- reported a surge in investment in the first quarter of 2026, underscoring efforts to strengthen infrastructure construction and support high-quality socioeconomic development in China.

The State Grid said it completed fixed-asset investment worth 129 billion yuan (about 18.77 billion U.S. dollars) in the first three months of this year, up 37 percent the corresponding period of the previous year. The spending has driven more than 250 billion yuan (36 billion U.S. dollars) of investment across the wider industrial chain.

Key projects such as the Panxi ultra-high-voltage (UHV) alternating current (AC) line and the Anhui-Hubei back-to-back direct current (DC) project have seen ground broken for their construction, while several west-to-east power transmission projects have been upgraded.

Investment in connecting renewable energy generation to the grid was reported to have exceeded 10 billion yuan (1.45 billion U.S. dollars) from January to March, a year-on-year rise of more than 50 percent.

The CSG also reported robust growth in investment in the three-month period, with fixed-asset investment reaching 38.45 billion yuan (5.58 billion U.S. dollars), up about 50 percent from a year earlier.

Among its achievements, the company completed and commissioned 80 key projects, including the 220 kV cross-sea power grid interconnection project, which was officially put into operation on March 20. The project ended years of grid isolation on the Weizhou Island in south China by linking it to the main power system of the Guangxi Zhuang Autonomous Region.

The construction of 17 other major energy projects, including one linking the power grid of the Xizang Autonomous Region in southwest China with that of Guangdong Province in south China, is advancing rapidly. These projects are expected to bolster regional industries, the maritime economy, digital collaboration and the transition to green energy.

"By accelerating major project construction, investment during the 15th Five-Year Plan period (2026-2030) is expected to approach 1 trillion yuan (145 billion U.S. dollars), driving a further 2 trillion yuan (290 billion U.S. dollars) of investment across upstream and downstream industries," said Dong Yanle, deputy general manager of the Engineering Construction Department under the China Southern Power Grid.
