On the 19th, the Jinggangshan warship, a landing ship detachment of the Navy of the Southern Theater, which was being sent to participate in the joint exercise of the "Golden Dragon 2023" between China and Cambodia, and two patrol boats from the Royal Cambodian Navy conducted a maritime cooperative navigation and communication exercise in the waters of Cambodia. "I am the Chinese Navy Jinggangshan Ship, and I am honored to visit your country and conduct exercises with you." "I am the Cambodian Navy Patrol Ship 1131, and I welcome the Chinese Navy Jinggangshan Ship to visit." At around 7 am local time, after nearly 100 hours of navigation, about 1300 nautical miles, the Jinggangshan Ship, which has just arrived in the waters of Cambodia, first conducted a maritime rendezvous and identification with two Royal Cambodian Navy patrol ships. In the subsequent cooperative navigation exercise, taking the Jinggangshan ship as the reference ship, the three Chinese and Cambodian ships cooperated with each other and completed the formation conversion training of single horizontal, single column, and cover formation in an orderly manner according to the predetermined course and speed. During the communication drill, the ships of both sides conduct communication drills while facing the designated sea area. At around 8:20, with the separation of the Chinese Jinggangshan ship and the Cambodian patrol boat, the maritime cooperative exercise was successfully concluded. Subsequently, the Jinggangshan ship docked at the Sihanouk port in Cambodia. It is reported that this is the first time that the Chinese and Cambodian armies have conducted maritime exercises. In the early stage, China and Cambodia conducted multiple consultations on the course exercise plan and the ship coordination plan, laying a good foundation for the successful completion of this exercise.
