The two sides enjoy deep political mutual trust, close exchanges on socialist development experience, and ever-stronger traditional brotherhood and friendly cooperation. The Cuban side firmly abides by the one-China principle, opposes external interference in China's internal affairs, and remains committed to advancing the building of a Cuba-China community with a shared future and opposing hegemonism.
