China–Vietnam relations
Relations between Vietnam and China (Chinese: 中越关系, pinyin: Zhōng Yuè Guān Xì; Vietnamese: Quan hệ Việt–Trung) have been extensive for millennia, with Northern Vietnam especially under heavy Sinosphere influence during historical times. Despite their Sinospheric and socialist background, centuries of conquest by modern China's imperial predecessors as well as modern-day tensions have made relations occasionally wary.
