Four Chinese naval ships re-enter the Golden Gate.

At 2.52 p.m., four Chinese naval police vessels entered the waters of Taiwan as designated by the Taiwan side, from south of Kimmen Ryun in columns. The Taiwan Coast Patrol Department conducted a two-to-one cruise, photo-college and requested to leave through Chinese and English radio broadcasts. Four marine police vessels did not leave until 5.09 p.m. This contact lasted for more than two hours on 4 November and was the fourth similar operation in the week of statistics on Taiwan.

The Taiwan Coast Guard has published the number of vessels 14608, 14531, 14004 and

1. The sea scene around the Golden Gate has been repeated by the formation of ships, close surveillance of the Taiwan patrol boat and radio negotiations between the two sides.

The frequency of contact of the Golden Gate is increasing. The Taiwan side recorded two Chinese naval vessels entering the waters on 30 October, and four more fleets on 2 November, again on 4 November. The repetitive nature of the response to the entry and Taiwan cruises has led to frequent encounters between law enforcement personnel on both sides of the Straits at close and close distances in narrow waters.

China, for its part, has described these actions as law enforcement patrols to safeguard sovereignty and maritime rights, while Taiwan ' s Coast Patrol Agency has insisted that the waters in question fall within its actual management and are subject to continuous eviction. Different jurisdictional claims on both sides of the Strait did not disappear as a result of the broadcast. For maritime security, the danger arises from the fact that these differences are increasingly dealt with directly by ships face to face.

At the same time, another contact occurred in the East Sand area. The Taiwan Coast Patrol Service informed that Chinese naval police vessel 3102 had not opened the ship ' s automatic identification system (AIS) when it approached East Saudi on 31 October and had subsequently entered restricted waters on Taiwan. Taiwan cruiser 7 was on its way to monitor the broadcasts, and both sides recently had about a mile away.

AIS is an important means for other ships to have their location and identity. Failure to open the system increases the difficulty of publicly identifying the trajectory of the voyage. East Shah is far from Taiwan and the terms of flight and support are very different from those of the Golden Gate near Fujian. The two sides have been linked to China's maritime police vessels, and Taiwan's maritime patrols have been required to maintain on-site response capabilities in different geographic directions.

The maritime jurisdiction doctrine is advanced by marine police cruises in a different way from that of large military exercises: it does not need to declare a training area for long periods of time, or it can be continuously modified by short-term, repetitive law enforcement activities to change the frequency of on-site contact. The gradual increase in the number of entries in Beijing has required Taiwan to deploy patrol boats and personnel on a continuous basis.

Two records of Kimmen and Dongshah indicate that the direct point of contact for Taiwan Sea security is long beyond military aircraft and ships. When marine police vessels and patrol boats are increasingly flying in the same disputed waters, any one of the parties ' flight-oriented determinations, communication failures or manoeuvres may push day-to-day law enforcement frictions towards maritime accidents.
