Friday’s dive was the first of a series of six leading up to a 7,000 meter.

The U.S. Fish and Wildlife Service told PNC News that the Chinese are diving in an area of the Mariana Trench that lies within the waters of the Federated States of Micronesia, in the area of the Challenger Deep, which is the deepest known area of all the world’s oceans.

The Challenger Deep lies south of the U.S. administered Mariana Trench National Marine Monument, which falls under the  jurisdiction of U.S. Fish and Wildlife.
