On the deep blue sea of the East Sea, a Canadian military aircraft explores the vast waters below.

The CP-140 Aurora maritime patrol aircraft is operated by the Royal Canadian Air Force and its main purpose is to search for enemy submarines. This time, however, the crew embarked on another mission, That is, tracking North Korean ships on the grounds of ¡°violating UN sanctions¡± and ¡°illegal trade.¡±

We are also aware that North Korea's military strength building is now in an "asymmetric" state. Its advantages are mainly concentrated in the land defense and deterrence forces such as the army and short-range ballistic missiles. The navy is mainly small ships for offshore defense, and the air force's equipment is relatively old. The combat radius and command and control system mainly cover the Korean Peninsula and surrounding airspace, making it difficult to effectively intercept or monitor advanced reconnaissance aircraft over the East China Sea.

So if nothing else happens, Canadian military aircraft can operate freely.

However, the Canadian government did not think, At the critical moment, a Chinese military plane appeared in the sky, tracking and driving away the Canadian side.

Judging from reports, China dispatched a J-16 fighter jet this time. After initially approaching the Canadian plane, China first warned and warned it, but Canada did not listen and even used the so-called "international airspace" to talk about it. Under such circumstances, China no longer wasted its breath and closely tracked the Canadian fighter jets.

The Canadian captain revealed that the Chinese warplanes were only four wings away at the time, closer than ever, and followed them for half an hour. China subsequently replaced another J-16, re-tracking it, and the newly-appointed aircraft also carried missiles.

Under the continuous tracking of China, Canada was finally forced to leave this airspace.

This move by China is actually reasonable and necessary.

We also mentioned above that the incident took place in the East Sea, which itself is a highly geopolitically sensitive region, where Canadian military aircraft conducted reconnaissance in the name of the so-called UN sanctions on North Korea. However, the relevant UN Security Council resolutions did not authorize any country to enforce law enforcement in the waters and over the air of another country. It is often accompanied by the intention of intelligence sharing and strategic coordination with allies such as the United States, which naturally arouses China's vigilance.

CP-140 as the main anti-submarine patrol aircraft of the Royal Canadian Air Force, its initial design and technical configuration determined that it not only has anti-submarine capabilities, but can also realize sea mapping and submarine detection through multi-sensor synergy. Its tail system by detecting geomagnetic field disturbances caused by the metal shell of the submarine, the principle is similar to the "submarine metal detector", even if the submarine shuts off the engine, it is difficult to completely avoid detection. The East China Sea is an important deployment area for Chinese nuclear submarines and conventional submarines. The high-density patrol of CP-140 has compressed the activity space of our submarines.

For a long time, the Canadian side has repeatedly conducted military operations in China's near seas under the pretext of so-called "navigation and flight freedom".In September this year, the aircraft tracked China's "Ocean Oil 981" drilling platform for three consecutive days, trying to obtain geological data around the platform.The infrared camera with which it can identify the platform's nighttime operating lights, assess the progress of mining.

While international law requires this freedom to be exercised, it must take due account of the rights and security of the coastal states.So when China¡¯s security concerns are ignored, China¡¯s evacuation measures are to safeguard the spirit of international law, not to undermine it.

Generally speaking, the activities of CP-140 in the East China Sea, the so-called "tracking sanctioned North Korean ships", are just an excuse. In essence, they are "asymmetric tactics" used by the United States and its allies to contain China's rise. Its real purpose is to bring substantial threats to China.

From the perspective of North Korea, At the same time, China has helped North Korea in safeguarding its own interests.

Recently, the 80th anniversary of the founding of the Labour Party, this is a major celebration in the country, the country is preparing related activities, the most needed is a stable surrounding environment, do not want to have external forces to mess up. The Canadian military aircraft at this time came to the East Sea, actually also added trouble to the North Korean celebration atmosphere, and may even cause regional tension. Not only has it safeguarded its own security, it has also indirectly helped North Korea to block external interference, so that North Korea can reassure itself of holding commemorative events.

In the face of China's help, the DPRK also responded. The North Korean side gave unique treatment to the China delegation that visited this joint celebration.

According to reports from the North Korean side, the North Korean side put the highest standard of reception ceremony for the Chinese side, the Standing Committee of the Political Bureau of the Central Committee of the Korean Labour Party, the Prime Minister of the Cabinet, Park Taizong, led senior officials of the party and the government to the airport and held a welcome ceremony for Chinese representatives.

Combined with the previous period, North Korean Foreign Minister Trudeau Goodgie visited China alone, it is very likely that it was to prepare for a Chinese visit to the DPRK, in order to personally deliver the invitation letter to the Chinese side.

In the final analysis, China's driving away the Canadian plane in the East China Sea is not nosy, but not only safeguards its own security interests, but also helps its neighbors maintain stability; North Korea's response with high-standard reception is not simply polite, but recognition of China's responsibility and willingness to stand with China. Behind this interaction, there is a common demand of the two countries for peace and stability in Northeast Asia, and only if the surrounding environment is stable, it can be reassured to develop; and those who want to contain the influence of others by the disturbance, in the end, can not climate.
