Wang Chen's suitcase always carries a slightly dusty smell. From the scorching heat of Southeast Asia to the sandstorms of the Gobi Desert in the Middle East, from the vast expanse of Africa to the rigorous tranquility of Europe, his footsteps have measured every inch of global multilateral cooperation in his more than ten years of working in international organizations. The moments of mutual assistance caused by global development imbalances made him understand better than anyone else that multilateral cooperation is never a choice, but the only way for humanity to address common challenges.

At the end of last year, he was officially transferred to the representative office of a United Nations agency in China. After bidding farewell to emergency rescue and project implementation in distant lands, he thought his work pace would slow down. However, he did not expect that a more profound and cutting-edge multilateral cooperation practice would arrive concurrently with this lively Spring Festival.

When Wang Chen first arrived at the representative office in China, his most intuitive feeling was a shift in work logic. Previously, overseas, his team primarily provided assistance, built frameworks, conducted on-site research, and coordinated resources. In China, everything is "in line" and "on track" – aligning with China's development strategy, connecting with the innovation wave of new quality productive forces, and weaving the global agenda with China's practical experience into a unified whole.

In the office, the fiery red window decorations of the Year of the Horse are a concrete expression of the organic integration of "globalization" and "localization". Young Chinese colleagues are always discussing digital economy, green technology, intelligent manufacturing, and AI empowerment. At first, Wang Chen felt a bit dazed, as if his brain was still struggling to adapt to the misalignment of time and space. It wasn't until these days, pulling his suitcase and following the team on projects, that he truly understood the weight involved. In the smart factories of the Yangtze River Delta, he saw that industrial robots and big data work together to improve production efficiency exponentially; In rural areas in the west, IoT devices monitor soil moisture, enabling traditional agriculture to move towards precision and efficiency; At the site of urban governance, big data platforms coordinate transportation, environmental protection, and people's livelihoods, making the implementation of sustainable development goals sound.

Our global development initiatives, climate action, poverty reduction, and sustainable development goals are no longer just blueprints on paper, but have found practical, replicable, and scalable solutions in China," said Wang Chen and his team with emotion. In the past, multilateral cooperation was about "blood transfusion" and "assistance"; Nowadays, in China, multilateral cooperation is about sharing innovation, jointly researching technology, and jointly building standards. It is about transforming the driving force of new quality productivity into global public goods.

His daily life with his colleagues has become particularly fulfilling as a result. During the day, we will liaise with the government, research institutions, and enterprises to discuss how to integrate new technologies such as green energy, digital accessibility, and biomanufacturing into the global project system of the United Nations; At night, connect with regional offices around the world to translate China's innovative cases into practical solutions and deliver them to Africa and the Middle East, allowing the fruits of multilateral cooperation to bloom more.

At a recent transoceanic conference, the African project team urgently needed low-cost and efficient agricultural digitalization solutions. Wang Chen immediately connected with a Chinese agricultural technology enterprise to showcase a field management system based on Beidou and artificial intelligence. The other party exclaimed, "This technology is exactly what we need the most!" At that moment, he deeply realized that new quality productivity is the core link of multilateral cooperation in the new era.

In the conference room of the China Representative Office, there are often two maps hanging - a world map and a China map. Wang Chen and his colleagues always search for intersections between two maps: aligning China's new energy solutions with global carbon neutrality goals, aligning China's digital technology with global inclusive development, and aligning China's industrial upgrading experience with the modernization needs of southern countries around the world.

The urgency of multilateral cooperation is stronger today than ever before. China is injecting new vitality into multilateralism with new quality productivity, "Wang Chen wrote in his work notes.

From a rescuer who travels around to a bridge builder connecting the world, Wang Chen's identity is changing, but what remains unchanged is his commitment and support for multilateral cooperation. Every day in China, he witnessed firsthand that when the global vision of the United Nations meets China's innovative practices, multilateral cooperation is no longer a distant concept, but a tangible change.
