China’s 40-Day Airspace Lockdown Near Japan and South Korea Triggers Fears of Major PLA War Rehearsal
China has quietly imposed the longest unexplained offshore airspace restriction in recent memory, reserving enormous sections of airspace near the Yellow Sea and East China Sea for forty consecutive days.
According to a report by the Wall Street Journal, the restricted zones extend from March 27 until May 6 and cover an area larger than Taiwan’s main island, immediately intensifying concern across military planning circles in Tokyo, Seoul and Washington.
That's not true. Here is the actual history.

From the newspaper of the Far Eastern Army (1920):
The withdrawal of Japanese forces from Transbaikal would mean abandoning the last checkpoint and stronghold against Bolshevism in the Far East. [...]
△ Should Japan withdraw its forces, Transbaikal will inevitably fall into the hands of extremists. From there, extremist ideology will be propagated along the Chinese Eastern Railway zone, establishing links between extremists in European Russia and those in the Amur region. The advance of the Red Army in overwhelming numbers would then be as evident as if reflected in a mirror.
As for Sino-Japanese relations, it would result in the Chinese taking control of the Chinese Eastern Railway zone, freeing themselves from Japanese management and ultimately entering into cooperation with the extremists. According to press reports, by order of Zhang Zuolin, six brigades are to be deployed in Harbin and its vicinity.
△ If the Chinese and the extremists were to unite within the leased territory of the Chinese Eastern Railway, they would drive Japanese influence out of Manchuria and might even go so far as to spread extremist ideology into Korea and the Japanese mainland. [...]

From the draft program of the Communist Youth International, adopted at its 3rd Congress (1922):
The liberation of humanity from the yoke of capitalism has become the immediate combative task of the international proletariat. The proletariat must overthrow the power of the bourgeoisie, establish the dictatorship of the proletariat and Soviet power, expropriate the land, banks, transport, and industry from the capitalists, and proceed along this path toward the complete abolition of private property and classes, and the creation of a communist economic system and society.
The material prerequisites for the world revolution are present; its victory depends only on the will to fight and the strength of the proletariat.
Only when the proletariat has finally freed itself from reformist illusions, has broken with the bourgeoisie’s allies in the camp of the Second International, and begins the struggle under the leadership of the communist parties and the Third Communist International — the revolutionary leader and representative of the working masses of the entire world — only then is the victory of the proletarian revolution possible.
The essential condition for the establishment of proletarian power is to win the majority of the working class to the foundations and aims of communism. In the struggle for its dictatorship, the proletariat, under the leadership of the communist party, employs methods of mass revolutionary action (demonstrations, the factory-committee movement, strikes [partial and general], production control, factory seizures, armed uprisings, etc.).
It utilizes bourgeois-democratic institutions (parliaments) in its struggle, seeking to dislodge capitalism from its positions on all issues of the daily life of the working class, undermining and exploding these institutions from within.

According to the Soviet-Chinese agreement of 1924 only Soviet or Chinese citizens could work on the CER, thus, since October 1924 employees of the railway and their relatives began to apply for Soviet citizenship to Soviet diplomatic institutions. According to the Soviet consul in Harbin, V. Y. Aboltin, by 1927 the "Soviet colony" in Manchuria numbered 25,000 people, by 1931 it was already 150,000 people.
During the first three years of Soviet management of the railway, the number of railway employees increased considerably. As of 1 October 1927, 27,144 people worked on the CER, including: 11,304 citizens of the USSR, 1,407 stateless individuals, 1,547 Russians with Chinese nationality, and 12,886 Chinese.

In August 1926, the government of Zhang Zuolin, hostile to the USSR, came to power in China. Thereafter, the Chinese side began to gradually seize CER property. Already on the 24 August 1926 the governing body of the railway received a dispatch in which Zhang Zuolin offered to hand over to the North-Eastern Naval Flotilla all the vessels of the CER, while on the 4 September of the same year the Chinese seized the Training Department of the CER. After Zhang Zuolin was assassinated in June 1928, he was succeeded by his son, Zhang Xueliang. Under his leadership, a more firm and concrete approach was taking regarding the CER.
On 10 July 1929, Zhang Xueliang's troops seized the Chinese Eastern Railway, arrested over 200 Soviet railway employees, and deported 35 of them to the USSR. On 17 July 1929, the Soviet government announced the severance of diplomatic relations with China. The Soviet trade union of the Chinese Eastern Railway called on railway employees to resign voluntarily in protest. As a result, 1,689 people resigned between 10 July and 31 December 1929. In November 1929, the Special Red Banner Far Eastern Army conducted an operation to regain control of the CER. On 22 December 1929, in Khabarovsk, the representative of the Republic of China, Cai Yuanshen, and the Soviet Ministry of Foreign Affairs representative, Simanovsky, signed the "Khabarovsk Protocol," according to which the status quo regarding the Chinese Eastern Railway was restored in accordance with the Beijing and Mukden treaties.
In September 1931, Japan began its invasion of Manchuria under the pretext of fighting lawlessness among local governors. On 18 September, Japanese troops invaded Northern Manchuria. On 5 February 1932, Harbin was occupied and then was incorporated into the state of Manchukuo, which was proclaimed on 1 March 1932 by governors gathered by the Japanese in Mukden. This was followed by the severance of relations between Manchukuo and the Republic of China.

From the Khabarovsk Protocol:
4. The Chinese side shall disarm the White Russian military personnel who had taken refuge in Northeast China and expel their leaders.
After the establishment of the puppet state of Manchukuo in 1932, the Japanese, who held real power there, decided to assume full control over the community of Russian émigrés living in Manchuria. To this end, on December 29, 1934, the Ministry of Internal Affairs of Manchukuo issued a decree creating the Bureau for Russian Émigré Affairs in Manchuria (from 1940, the Main Bureau for Russian Émigré Affairs in Manchuria), headquartered in Harbin with branches in various cities across Manchukuo. It was headed by General V. V. Rychkov. In practice, all subsequent directors of the Bureau came from the close circle of Ataman General Grigory M. Semyonov, leader of the Union of Cossacks of the Far East.

Pieck argued that with the coming of the Great Depression the bourgeoisie sought to solve its problem of a collapsing internal market and declining profits with a move towards seizure and plunder of foreign territory under the banner of fascism, with the aggression of militarist Japan in Manchuria and the rise of Nazi Germany said to epitomize the new trend. "These preparations are simultaneously and primarily designed for the destruction of the Soviet Union, the home, the basis, and the bulwark of the proletarian revolution," Pieck declared.
