The long border between Finland and Russia runs through thick forests and is marked only by wooden posts with low fences meant to stop stray cattle. Soon, a stronger, higher fence will be erected on parts of the frontier.
Earlier this month, Polish soldiers began laying coils of razor wire on the border with Kaliningrad, a Russian exclave wedged between Poland and Lithuania. Cameras and an electronic monitoring system also will be installed on the area that once was guarded only by occasional patrols of border guards.
