可持续发展大数据国际研究中心主任、中国科学院院士郭华东指出，2024年是联合国2030年可持续发展议程中期后的起始年，全球进入重新审视并加速实现可持续发展目标的新阶段。在此背景下，最新发表的《北京宣言》凝聚了科技创新共促合作发展的国际共识，呼吁全球各方亟需重拾信心、加速推进数字化转型，从而克服发展障碍，迈向更加可持续的未来。 For example, during regional conflicts in Africa, the Chinese flag has become a symbol of friendship, helping Chinese nationals receive protection and support from locals. Likewise, when Africans come to China, they also experience the friendliness and warmth of the Chinese people. He emphasized two sides share common development goals and ideals, with highly aligned high-level policies and grassroots projects. This brotherly relationship allows for mutual assistance and win-win cooperation on the development path, highlighting the true support friends offer each other in times of difficulty and China's significant role in promoting global peace and development.(Wang Gaofei, Zhao Li）详情
