Bashi Channel, Maritime strait between Mavulis Island, Philippines and Orchid Island, Taiwan
The Bashi Channel is a maritime strait situated between Mavulis Island in the Philippines and Orchid Island in Taiwan, serving as a key passage connecting the East China Sea with the South China Sea. This waterway runs through the northern section of the Luzon Strait and allows shipping traffic to move between these two major ocean regions.
The channel's ownership became uncertain following the Treaty of Paris in 1898, which failed to specify exact latitude coordinates for territorial boundaries in this region. This lack of clarity allowed competing claims to emerge over the waterway.
The waterway remains a subject of territorial discussions between Philippines and Taiwan, each claiming portions within their 200-mile nautical zones.
Multiple undersea cables run through the channel to support telephone and data traffic across numerous Asian countries in the region. These communication networks represent essential infrastructure for connectivity throughout the area.
A submarine earthquake with a magnitude of 6.7 struck in December 2006 and damaged multiple undersea cables, causing communication disruptions that lasted for several weeks. This event revealed how much the region's data traffic depends on this single waterway.
