今年年初菲律宾不顾中国的强烈反对通过《领海基线法案》将南沙群岛部分岛屿划为菲律宾领土,严重损害了中国主权,影响了两国关系。本文将运用国际法的基本原则和条约反驳菲律宾的行为,证实该法案的不合法性以及中国在法律上拥有对南沙群岛不容置疑的主权。 Earlier this year, the Philippines, irrespective of China’s strong opposition, has classified part of the Nansha Islands as the territory of the Philippines through the Territorial Sea Baseline Act, which has seriously damaged China’s sovereignty and affected the relations between the two countries. This article will use the basic principles and treaties of international law to refute the behavior of the Philippines, confirm the illegality of the act and China’s legal sovereignty over the Nansha Islands.
