China Launches 16th Arctic Expedition with Four-Ship Fleet

China launched its 16th Arctic Ocean scientific expedition on July 3, 2026, as a fleet of four research vessels departed from the northeastern port city of Dalian, Liaoning Province. Organized by the Ministry of Natural Resources, the mission is expected to be completed by early October and marks China’s first Arctic expedition under the 15th Five-Year Plan (2026–2030), according to CCTV News.

A Growing Polar Research Capability

Three icebreakers — Xuelong (“Snow Dragon”), Xuelong 2 (“Snow Dragon 2”), and Jidi (“Polar”) — set sail together from Dalian on Friday, with a fourth vessel, the multifunctional research ship Tansuo 3 (“Exploration 3”), scheduled to join the expedition later, as China Daily reported.

The four-ship deployment represents a significant demonstration of China’s growing indigenous polar research infrastructure. Xuelong 2, China’s first domestically built polar icebreaker, entered service in 2019, while Tansuo 3 adds multifunctional research capabilities to the fleet. Before departing, Xuelong and Xuelong 2 were opened for public visits in Dalian on July 1–2, receiving approximately 2,000 visitors in a public diplomacy effort to showcase China’s polar research achievements.

Research Focus: Climate Change at the Core

The expedition’s primary focus is addressing global climate change and its impacts on the Arctic region. Researchers will conduct comprehensive surveys and monitoring in key areas of the Arctic Ocean, with investigations covering sea ice, hydrology, biology, ecology, and the atmospheric environment, according to Xinhua News Agency.

The team will also study frontier scientific topics, including the accretion mechanisms of the Gakkel Ridge and the dynamic evolution of the oceanic crust — research that could advance understanding of fundamental geological processes in one of the planet’s most remote regions.

Wang Jinhui, leader of the 16th Arctic expedition, emphasized the urgency of the mission, stating: “Currently, driven by global warming, the Arctic natural environment is undergoing rapid and profound changes, with sea ice melting and other trends intensifying. This concerns the common destiny of human survival and development, and has global significance and international impact.”

The Ministry of Natural Resources echoed this framing, noting in an official statement that “sustained comprehensive Arctic expeditions serve as a critical foundation for addressing global climate change and advancing the sustainable development of the Arctic region.”

International Collaboration

The expedition includes joint research with scientists from Russia, Germany, and other countries, reflecting China’s emphasis on scientific diplomacy in the Arctic. The ministry stated that this cooperation aims to provide “scientific support for China and the international community to better understand and protect the Arctic region and improve Arctic governance,” as Bastille Post reported.

Domestic Technology Milestone

Professor Li Wenhua of Dalian Maritime University, who participated in China’s 15th Arctic expedition, highlighted the growing role of domestically developed equipment in polar research. Li led the development of an advanced winch system for deep-sea exploration operations that completed a successful trial during the previous mission.

“Today, domestically developed equipment is being increasingly deployed in polar expeditions. This is the greatest achievement for us deep-sea science and technology researchers,” Li told China Daily.

Strategic Context

China’s Arctic engagement has deepened steadily since its first official Arctic Ocean expedition in 1999. The country obtained observer status in the Arctic Council in 2013 and has since positioned itself as a “near-Arctic state,” emphasizing scientific research, environmental protection, and sustainable development in the region, as outlined in its 2018 Arctic Policy white paper. According to Wikipedia, China has conducted Arctic expeditions annually since 2016.

The 16th expedition also takes place against a backdrop of intensifying geopolitical interest in the Arctic. Melting sea ice has opened new shipping routes and resource extraction possibilities, drawing attention from both Arctic and non-Arctic nations. China’s joint research with Russia is particularly notable given the broader strategic partnership between the two countries.

Looking Ahead

With the expedition expected to continue through early October, researchers will spend approximately three months collecting data and conducting experiments in some of the world’s most challenging environmental conditions. The findings are expected to contribute to international understanding of Arctic climate dynamics and inform policy discussions on Arctic governance and environmental protection.

China’s 15th Arctic expedition, launched in July 2025, was the country’s largest-ever Arctic mission, also involving four vessels. The 16th expedition builds on that foundation, signaling China’s continued commitment to expanding its polar research capabilities under the new Five-Year Plan period.
