While Japan and South Korea are also conflicting over the issue of sovereignty over the Doko-Takeshima Islands, both countries agree that Russian bombers are not allowed to fly over these islands.
According to CNN, four countries Japan , South Korea , Russia and China a few days ago caught the attention of bombers, warning Russia early on patrolling at sea with Chinese aircraft.
It is worth mentioning that Russia's A-50 early warning aircraft "mistakenly flew" into a 12-nautical-mile sky from the disputed island with Japan. Moscow later admitted that the pilot was mistaken, possibly due to technical problems.
The Japanese side also tried to stop the fight because of claims to the islands.
Disputes for hundreds of years
The Japanese side affirmed that the Takeshima archipelago belonged to Japan. Japanese officials accused Russian aircraft of invading Japanese airspace and South Korean airplanes were not allowed to fire like that.
The case may exacerbate Korea-Japan relations, which are already very tense when the two sides constantly retaliate.
The Japanese Foreign Ministry said it had claimed the islands since the 17th century, when fishing vessels came here to hunt sea lions and harvest abalone.
The Japanese side said under the San Francisco Treaty in 1952, the US recognized the Japanese Takeshima Islands, not in the occupied islands that had to be returned after World War II.
South Korea said that they were sovereign islands earlier than Japan, from the 15th century and called the Dokdo archipelago.
Korea also cited a map of Japan in the late 1800s, when it was still recognized as a Korean archipelago. In 1906, Korea considered the Dokdo Islands as Gyeongsangnam-do Province.
Today's uninhabited Dokdo / Takeshima Islands continue to fall into a spiral of dispute between the East Asian neighbors.
Opportunities of Russia and China
Japan and South Korea could not solve the maritime sovereignty disputes, how could the US implement international order, especially in the issue of Crimea or East Sea?, CNN asked questions.
Analysts said it was an excuse for Russia to divide East Asian countries with the United States, for its own sake
"The US is currently trying to persuade its East Asian allies to support their position on the Korean or Iranian issue. Korean-Japanese tensions will further complicate the problem, ”said Timothy Health, an analyst at US-based RAND Group.
Analysts say Russia has deliberately put A-50 aircraft into Korean / Japanese airspace to try to see how the Korean military will react, activate the defense system. The A-50 was dubbed the "god eye", with powerful sensors and radar, easily detecting abnormal signs from afar.
"The A-50 will collect electronic signals, radio, communications, to assess the Korean side's ability to react," said expert Peter Layton, a former Australian pilot and currently working at Griffith Institute. "Since then, Russia will draw a map of Korean air defense."
Besides, the emergence of Chinese aircraft also sent a message to Washington about Russia-China cooperation.
"What is remarkable is the unprecedented level of Russian-Chinese cooperation," said Carl Schuster, professor at the Pacific University of Hawaii, former director of the General Intelligence Center of the US Pacific Command. , to speak.
International relations expert, Artyom Lukin, from Vladivostok University, said, "Russia and China have joined hands to send messages to Japan, South Korea and the United States."
"China and Russia are showing the closest relationship since the 1950s and this relationship will continue to be tightened in the coming years."
That's why the uninhabited Dokdo / Takeshima Islands have become the focus of a tense confrontation between the four countries of Russia, China, Japan and Korea.
