Concurring means agreeing or being in harmony, which contradicts the idea of trying to bridge differences. Collaborative implies working together, which does not convey the idea of differing views. Varied refers to differences in types or forms, but it doesn't emphasize strong opposition or conflict between views as "divergent" does. The sentence refers to the efforts of countries to bridge differences in views on how to address plastic pollution. "Divergent" (meaning differing or going in different directions) fits best because it emphasizes the conflict or opposition in the views held by different countries.
