The incident highlighted that China considers the Taiwan Strait a domestic waterway, and it was an attempt to demonstrate its military hegemony, they said. Crew on the Canadian vessel contacted the Chung-Hoon after seeing the Chinese vessel alter its course and told the US ship to move to avoid a collision, Global News said. The US destroyer responded by asking the Chinese warship to steer clear of the ship, but it ultimately needed to change course and decelerate, it said. The 1972 International Regulations for Avoiding Collisions at Sea stipulate that the Chinese frigate should have yielded and avoided the US vessel, he said. Should the situation permit it, the ship should avoid crossing the bow of the other ship, the regulations say.
