China and Finland have agreed to deepen joint research on climate and cold regions by combining respective strengths in remote sensing and snow science, said Qiu Yubao, a professor at the Aerospace Information Research Institute under the Chinese Academy of Sciences (CAS).
As climate change accelerates across cold regions, particularly the Arctic and Pan-Arctic regions, China and Finland signed an agreement on April 8, 2018 to establish a joint research center for Arctic space observation and data sharing services.
The collaboration combines China's advanced remote-sensing technologies with Finland's world-leading expertise in snow and ice science.
In an interview with China Global Television Network (CGTN), Qiu, who is also the director of Digital Environment Division under the International Research Center of Big Data for Sustainable Development Goals (CBAS), explained that the shared scientific needs in vast snow-covered regions and complementary technological strengths brought the two sides together.
"In snow research, particularly studies of snow cover, Finland is at the global forefront. China, on the other hand, has comparative advantages in remote sensing observation technologies. Both countries have vast snow-covered regions and broad application scenarios," said Qiu.
Qiu then introduced a major breakthrough in coupling physical models with remote sensing technologies.
"In recent years, especially from 2023 to 2025, a major breakthrough has been the coupling of physical snow and ice process models with microwave remote sensing models. This has become a frontier topic internationally, enhancing both sensor observation capabilities and our understanding of Earth's geophysical processes. We are also jointly developing new technologies, such as atmospheric corrected high-frequency detection of new snow, based on the experiments. These studies can provide strong support for emergency monitoring of snow-related disasters in southern China, especially for the humid atmosphere and shallow snow cover area," he highlighted.
Qiu also shared a profound personal memory from the demanding fieldwork.
"Experimental work is demanding, sometimes we had to go outdoors in the middle of the night to wait for satellite overpasses and conduct synchronized ground measurements. That was when I saw the aurora for the first time. The sky was completely covered in blue-green light. I was walking alone in the snow, with dogs barking in the village nearby. I was terrified at the time, but it has since become one of my most beautiful memories," Qiu said.

South China's Guangdong Province is accelerating its transformation into an international medical tourism hub, positioning itself as a destination for patients worldwide seeking affordable, high-quality care.
The push follows a joint initiative announced in late March by nine Chinese government departments, including the Ministry of Commerce, aimed at boosting spending by foreign tourists and enhancing exports of tourism services as part of broader efforts to expand the country's service sector.
Every day, some of the most complex surgeries are performed here. Li Zilun, deputy director of the division of vascular surgery at the First Affiliated Hospital of Sun Yat‑sen University, is among the doctors capable of carrying out these intricate procedures.
He recently completed surgery on a patient with an aortic aneurysm, a condition often described as a "time bomb" in the body’s main artery, increasingly common in aging societies around the globe. Li also specializes in highly difficult and pioneering procedures, including repairing leaks caused by failed grafts.
"This was a very challenging case. And then, we implanted the covered stent to eliminate the endoleak. Actually, the outcome was pretty good. The patient will be discharged today," said Li Zilun.
The ability to handle such complex cases -- combining international techniques with domestically produced devices -- is drawing patients from around the world to seek treatment. In addition, high safety standards and low costs are also major draws.
"Our government is encouraging innovation. So, lots of physicians -- including our vascular surgeons -- we are actively involved in the innovation that helps to increase the effectiveness and safety, and also bring down the cost," said Li.
This hospital is one of the first in Guangdong to be designated by the provincial health commission as a pilot site for building an international medical service hub.
The growing number of patients has pushed the hospital to explore new ways to transform every step -- from treatment to payment and everything in between -- into a seamless experience, reducing waiting times and delivering better care for patients.
"I think it's fast. When the patient come here for just about, I think, one week, you can solve the problem," said Xiao Haipeng, president of the First Affiliated Hospital of Sun Yat-sen University.
The hospital is also deepening its international cooperation with top-tier medical institutions, including those at Harvard University.
"Not just for China, for the whole globe, we are facing health care challenges -- emerging infectious disease and chronic, lung infectious diseases, and also the aging population, also the shortage of healthcare workforce," said Xiao.
In response to these challenges, China is promoting its own solutions, including aggressive innovation in artificial intelligence (AI)-driven workflows, while stepping up research and development investment and global engagement along the way.
"In recent years, the innovation in Western medicine is dramatically growing. An example of my hospital -- in the past few years, we have 140 innovations and seven of them are international leading innovations," said Xiao.
As global demand for medical tourism grows, China is positioning itself as a new destination. Official data shows that the number of foreign patients in Guangdong increased by 20 percent last year. Among them, the growth in inpatient admissions was even faster, rising by 76 percent.
