Beijing’s interest has intensified disputes with other countries in the region in recent years, especially since China has increased its naval presence. Despite rising international pressure, including an unfavorable ruling by the International Tribunal for the Law of the Sea, China staunchly defends its policies in the region. Preventing tensions from boiling over is a matter of careful diplomacy.
