In the context of military conflict, skirmish refers to a small-scale noncommittal war or fighting. It happens in disputed areas, when patrols of different countries claim the same territory and start shooting at each other, but their commanders pull back before the battle escalates to full-scale war. It’s also used to describe sporadic small-scale fights between units, usually a mobile and light one, such as roman auxiliaries or modern light motorized units. They’re designed to scout and harass an enemy, to hit them at their weak spots, to distract and confuse them.
The current scuffle between India and China along their disputed border in the western Himalayan region has become a major source of tension. While both countries want to avoid open hostility, tensions remain high because of the potential for escalation — and that would threaten international stability. It would also harm both economies, as trade between the two is vital.
A key reason for the tension is an ill-defined 3,440km (2,100 mile) disputed border. Rivers, lakes and snowcaps can shift the border at many points. The line is also a result of historical treaties that include vague language or have been interpreted differently by the parties involved. Disputes over borders are frequent and a common cause of international armed conflict.
The current face-off between the two world powers has ratcheted up tensions, despite an ongoing diplomatic effort to find a peaceful resolution. But a return to open hostility could be dangerous because of both countries’ established nuclear weapons and their economic stake in each other’s success.
