Great to Know

• Despite repeated border tension, India and China remain major trading partners.
• This is the relationship’s central contradiction: deep economic ties alongside an unresolved border.

• This means periodic flare-ups are a recurring feature of the relationship, not one-off incidents.
• This pattern isn’t unique to China. India’s Kashmir dispute with Pakistan follows a similar path — diplomacy, without full resolution.
