International collaboration refers to the cooperative efforts between countries to address common challenges and achieve shared goals. This can involve various sectors, including science, education, and environmental protection. By working together, nations can pool resources, share knowledge, and leverage diverse perspectives to tackle issues that transcend borders, such as climate change and public health. Such collaboration often takes place through organizations like the United Nations or World Health Organization, which facilitate dialogue and joint initiatives. Additionally, international partnerships can enhance cultural exchange and promote peace, fostering understanding and goodwill among different nations and peoples.
