Zhang Junshe, a researcher at the Naval Research Institute, told the Global Times on the 19th that according to relevant international law, the Tsugaru Strait is a non-territorial strait that applies the system of freedom of navigation and overflight, and warships of all countries enjoy the right to normal passage. The formation of Chinese and Russian naval vessels sailing into the Pacific Ocean through the Tsugaru Strait is fully in line with international law and practice, and individual countries should not make irresponsible remarks about this.
