Back to basics: Maritime Security and Territorial Disputes
Maritime security involves protecting a nation's sovereignty and economic interests in its surrounding waters. Territorial disputes arise when two or more countries claim sovereignty over the same maritime areas or islands. In such disputes, coast guards and naval forces often patrol and enforce claims, sometimes leading to confrontations. The South China Sea is a key example where multiple countries assert overlapping claims, making it a hotspot for regional security tensions.
