The USCGC Oliver Henry (WPC 1140) crew arrives in Manus, Papua New Guinea, on Aug. 14, 2022, from Guam as part of a patrol headed south to assist partner nations in upholding and asserting their sovereignty while protecting U.S. national interests. The U.S. Coast Guard is participating with partners to support the Pacific Islands Forum Fisheries Agency-led Operation Island Chief and the larger Operation Blue Pacific through patrols in the Western Pacific in August and September 2022.

“The United States Coast Guard is in talks with Pacific Island countries to expand its maritime law enforcement role by allowing U.S. officers to board and search vessels suspected of illegal activity within their economic zones, officials said.”
This is about expanding and streamlining the shiprider program. In one case the Coast Guard already have permission to work with a national command center and act on behalf of another nation, Federated States of Micronesia, even if there is no shiprider physically aboard the cutter.
“More specifically, the agreement provides a coordinating mechanism and process for U.S. law enforcement personnel to work with the FSM National Police through command centers to receive approval from the FSM to act.”
Thanks to Lee for bringing this to my attention.

“The Maritime Character of the Russo-Ukrainian War”

The proposed Ukrainian countermeasures to Russian attacks of grain shipping would only work against surface vessels. The Russians could use submarines or aircraft with relative impunity. They would not even have to sink every grain ship, just holding them at risk would be sufficient.
Rather they develop good transportation from Ukraine into Romania. Attacking shipping to and from Romanian ports would be an escalation the Russians would not be wise to do.
This was written before the Grain deal collapsed, but it discusses Russian alternatives for attacking grain ships. http://www.hisutton.com/How-Russia-Could-Torpedo-The-Grain-Deal.html
