Bashi Channel

The Treaty of Paris in 1898 specifically said: "the northernmost part of the Philippine territory ceded by Spain to the U.S. ends at the 20th parallel, or south of the Balintang Channel."

The Bashi Channel was not included here because original treaties signed in this period of time didn't use latitude and longitude.

The Philippines and Taiwan dispute the ownership of the waters because both sides say the region lies within 200 nautical miles (370 km; 230 mi) of their shores.

Many of the undersea communication cables that carry data and telephone traffic between Asian countries pass through the Bashi Channel, making it a major potential point of failure for the Internet.

In December 2006, a magnitude 6.7 submarine earthquake cut several undersea cables at the same time, causing a significant communications bottleneck that lasted several weeks.
