The Spratly Islands are disputed by many states in the area, and a large portion of the South China Sea is claimed by China. Unlike its neighbours of Vietnam and the Philippines, Malaysia historically avoided conflicts with China. However, after the encroachment of Chinese ships in Malaysian territorial waters, Malaysia has become active in condemning China. Brunei and Malaysia in 2009 announced an end to claims of each other's land, and committed to resolve issues related to their maritime borders. The Philippines has a dormant claim to the eastern part of Sabah. Singapore's land reclamation has caused tensions, and minor maritime and land border disputes exist with Indonesia.
