Background to Song Jiaoren and Lin Boqu's Sino-Korean border operations

In 1904, the Russo-Japanese War for hegemony in East Asia broke out. Japanese imperialism, supported by the British and American powers, defeated the corrupt Russian Empire. Japan then accelerated the pace of annexation of Korea, while colluding with Tsarist Russia to reject the expansion of the US imperialist forces on the northeast mainland of China, and the northeast continent was divided and occupied by Japan and Russia.

In May 1906, the Cabinet of Saienji, Japan, secretly convened the "Manchurian Council" and formulated the policy of "Japan recognizing the northern part of northeast China as Russia's sphere of influence" in exchange for "Russia shall not invade the Japanese sphere of influence south of Changchun".

In December 1906, the Cabinet of Saienji Temple in Japan used the excuse that "the territory of Majima has not been determined" and formulated the "Majima Governor's Office Establishment and Majima Gendarmerie Formation Table".

In February 1907, the Saienji Cabinet decided to set up the "Temporary Police Station of the Imperial Household OfmaJima" and sent a secret telegram to the Japanese minister stationed in Beijing, informing: "First, with Sasato Yoshijiro in the army as the main brain, military police and police will be dispatched."

In April 1907, Saito and his assistant Osamu Shinoda led a group of military police to infiltrate the territory of Majima Island to conduct surveying and mapping and detective activities. By July, it numbered more than 300.

On July 30, 1907, the Japanese and Russian governments sent representatives to sign the "Russo-Japanese Treaty" and the "Russo-Japanese Secret Treaty" in Moscow, which clearly stipulated the "mainland policy" of dividing the northeast China. The emergence of Japan's "mainland policy" marked that the pace of Japan's invasion of China's three eastern provinces had entered a substantive stage.

The so-called "Inter-Island"

In August 1907, the Japanese sent people to break into Longjing Village, Yanji County, Jilin Province, and set up the Japanese Police Station of the Korean Government without authorization to create the so-called "Between Islands" (when Japan and South Korea called the four counties of Yanji, Wangqing, Helong, and Hunchun in China's Jilin Province "Between Islands"), in an attempt to divide China's territory and cause Sino-Japanese negotiations, which lasted for two years. After several negotiations, the two sides finally reached an agreement.

On August 19, The Japanese imperialists set up the "Provisional Police Station of the Imperial Household Ofmajima" in Longjing, with Saito as the director, Sada as the deputy director and chief of the General Affairs Division, Akira Ogawa as the chief of the Investigation Division, the Army Gendarmerie Minoru Kiyano Takejin as the police chief and head of the gendarmerie detachment, and Choi Kinan as the chief of the Supervision Division. The purpose of the Japanese imperialist establishment of the "Majima" Temporary Police Station of the Imperial Supervision Office was to "merge the Majima Islands, which originally did not belong to either side of the Qing and South Koreas under international law," into Korea.

Japanese imperialism regards Yanbian as a bridgehead for the implementation of the "mainland policy" to invade and occupy the northeast Mainland of China, spreads the argument that the "Inter-Island Issue has not been resolved", and creates the so-called "Inter-Island Issue" under the pretext of "protecting the lives and property of the Korean people on the Inter-Island". In order to solve this so-called "Inter-Island Problem", on August 23, 1907, the sign "The Temporary Police Station of the Imperial Household Of the Imperial Household" was hung up in Longjing, and a gendarmerie team was set up, equipped with 54 gendarmes. The essence of the so-called "Inter-Island Question" created by Japanese imperialism is to occupy Yanbian, China.

On September 4, 1909, Liang Dunyan, Minister of The Shangshu Association of the Ministry of Foreign Affairs of the Qing Government, and Yanji Ijiin, Japanese Minister to China, signed these Terms and Conditions in Beijing, with a total of 7 paragraphs. Attached are 1 note verbale between China and Japan. After the signing of the articles, Japan's ambition to divide the territory of our northeast was unsuccessful. On November 1, Japan closed the "Imperial Household Majima Temporary Police Station" and on November 2 opened the so-called "Majima" Japanese Consulate General, strengthening its aggressor institutions. Since then, Japan has begun to intervene politically in the "Inter-Island" issue, which has become the main breakthrough point for Japanese imperialism to implement the "mainland policy" and invade and occupy northeast China.

Later, in order to strengthen the management of the Yanbian area, the Qing government upgraded the Yanji Hall located in Juzi Street to "Yanji Province". The Treaty is available in only Chinese and Japanese texts. There was no Korean text, but korean documents were mostly translated by themselves, and unilaterally called it the "Inter-Island Treaty" or "Inter-Island Treaty"
