China Focus: China, Denmark to deepen cooperation on green innovation
BEIJING, May 21 (Xinhua) -- Senior officials and scholars from China and Denmark have pledged to deepen cooperation on green innovation during an event marking the 75th anniversary of diplomatic relations between the two countries.
Scientific and technological cooperation has always been an important part of China-Denmark relations, contributing significantly to economic development, social progress, and the improvement of people's livelihoods in both countries, noted Chinese Minister of Science and Technology Yin Hejun.
He made the remarks while addressing the China-Denmark Green Research & Innovation Day, held simultaneously in Beijing and Copenhagen on Monday (Beijing time).
In the face of pressing global challenges like climate change, it is more important than ever for countries, including China and Denmark, to strengthen exchanges and cooperation in jointly advancing green and zero-carbon sustainable development, he said.
Yin emphasized green innovation as a key direction in bilateral sci-tech cooperation. China is steadfast in pursuing its green development path, he stressed, noting that Denmark, a global pioneer in the green transition, has achieved remarkable success in renewable energy, green transportation and resource recycling that offer valuable lessons for China.
Monday's event was jointly hosted by China's Ministry of Science and Technology and Denmark's Ministry of Higher Education and Science. It featured a series of activities, including the China-Denmark Cooperation Forum on Science, Technology and Innovation. The Beijing venue of the event was the Sino-Danish College (SDC) under the University of Chinese Academy of Sciences.
The two countries signed a number of cooperation agreements covering policy alignment, technological research and development, and industrial incubation at the event.
Speaking at the event, Chinese Ambassador to Denmark Wang Xuefeng said that China and Denmark share broad consensus on addressing climate change, advancing global sustainable development, and promoting open international cooperation in science and technology.
China is ready to work with Denmark through cooperation in sci-tech innovation to explore solutions to global challenges, jointly address the challenges of the times, foster shared peace and development, and help build a global sci-tech community, Wang noted.
Christina Egelund, Minister of Higher Education and Science of Denmark, delivered a speech at the event and reaffirmed commitments of the two countries to addressing global challenges and taking effective action to promote a stronger, greener and healthier global development.
"We have agreed to work towards these goals by cooperating in areas of mutual interest within science, technology, innovation and higher education," she said, adding that the event proved that "we are committed to putting action into achieving our shared goals."
Anders Siegumfeldt, Deputy Head of Mission at the Embassy of Denmark in Beijing, said in his video speech that China and Denmark do share a common goal of building greener societies.
Highlighting Denmark's collaboration with Chinese institutions and businesses on innovative solutions -- from offshore wind and green urban planning to sustainable agriculture and clean energy systems -- he called for the two countries to continue working together toward a more sustainable and prosperous future.
China and Denmark have jointly convened 21 sessions of the Joint Committee Meeting on Scientific and Technological Cooperation. The cooperation in technological innovation between the two countries has continued to deepen, with increasingly close connections between science and technology authorities, universities, research institutions, and enterprises. Significant achievements have been made in scientific collaboration and exchanges across fields such as energy, environment, water resources, healthcare, agriculture, and green development.

Chinese scientists unveil new anti-tumor immune mechanism
BEIJING, June 25 (Xinhua) -- Chinese researchers have uncovered a previously unreported immune-activating function of methotrexate, a classic immunosuppressive drug, providing a theoretical foundation for its combined use with tumor immunotherapy and radiotherapy in clinical practice.
The findings have been published online in Science Translational Medicine.
While significant progress has been made in tumor immunotherapy in recent years, challenges of primary and acquired drug resistance persist.
In this study, the research team revealed methotrexate's previously unrecognized immune-activating role within the tumor microenvironment, said Zheng Mingyue, corresponding author of the paper and researcher at Hangzhou Institute for Advanced Study, University of Chinese Academy of Sciences.
The team developed a novel algorithm predicting that methotrexate exerts its anti-tumor immune effect by inhibiting ENPP1, an enzyme widely distributed across various human tissues and cells.
The research demonstrated that low-dose methotrexate treatment not only significantly enhanced the anti-tumor efficacy of immunotherapy and radiotherapy in mouse models but also played a similar synergistic role in preliminary clinical trials.
According to the results, methotrexate treatment can enhance the efficacy of radiotherapy and help overcome the drug resistance of tumors to immune checkpoint blockade therapy.
This discovery provides a theoretical basis for combining methotrexate with radiotherapy or immunotherapy, Zheng said, adding that it also paves the way for novel anti-tumor drug development strategies and holds significant clinical translation value.
