North Korea and China are each other's lips and teeth, and the two countries have a friendship of thousands of years. During the Tang Dynasty, the Yuan Dynasty, the Ming Dynasty, and the Qing Dynasty, Japan sent troops to invade the Korean Peninsula on a large scale, but the ancient Chinese dynasties all sent large armies to support it, so that the Korean Peninsula was not invaded by the Japanese.
After the end of the Sino-Japanese War, the Korean Peninsula was occupied by the Japanese, but the Korean people did not give up resistance, and many Koreans ran to China, hoping to help Korea recover after the Chinese completed the democratic revolution. In 1909, Japanese Prime Minister Itō Hirobumi was assassinated in Harbin by the Korean Yoshinori Ahn Jung-geun and was killed on the spot. In 1932, during the Battle of Songhu, the 19th Route Army rose up to resist the japanese invasion, and Wang Yaqiao, the leader of the Axe Gang, sent a Korean righteous soldier to successfully assassinate the Japanese commander in Shanghai, General Shirakawa Yoshinori.
There are also many North Koreans in the Whampoa Military Academy. After Chiang Kai-shek launched the April 12 counter-revolutionary incident, some Koreans followed him to Nanjing, and some followed the Chinese Communist Party, Chinese the founder of the early artillery of the People's Liberation Army, the head of the artillery regiment of the Eighth Route Army Headquarters, and later the commander of the Second Army of the Korean People's Army, Wu Ting, the second secretary of the Workers' Party of Korea, participated in the Long March. Later Chairman of the Workers' Party of Korea Kim Il Sung was also a subordinate of Yang Jingyu, and after the Northeast Anti-Japanese Coalition retreated to the Soviet Union, it was reorganized into the 88th Brigade of the Far East International of the Soviet Red Army, and the commander of the 88th Brigade, General Zhou Baozhong, was the deputy commander of the Northeast Democratic United Army, and Kim Il Sung was his battalion commander.
After the end of the War of Resistance Against Japanese Aggression, 100,000 officers and men of the Eighth Route Army immediately went to the northeast region and occupied major cities in the northeast. However, after the liberation war broke out in full swing, Chiang Kai-shek quickly sent troops to the northeast with the help of the Americans. The first to go to the northeast were the elite of the nationalist army, and many of them were also units that had participated in the expeditionary force, with excellent weapons and powerful firepower, which made the northeast field army suffer a lot of losses. Especially after the Battle of Siping, Northern Manchuria and Southern Manchuria were cut off by the Kuomintang army, and the Northeast Field Army fell into a state of running out of ammunition and food.
At the most difficult time for the Northeast Field Army, North Korea decisively extended a helping hand, and Kim Il Sung, chairman of the Workers' Party of Korea, said that he would treat the Chinese revolution as his own. He also called on the people of the whole country to tighten their belts and fully support the liberation war in the northeast. Kim Il Sung also carried out special activities in Korea, allowing the whole country to collect weapons and ammunition left over from the Japanese occupation period, and collected a large number of weapons and ammunition in a month's time, including 82 guns, 60 guns, mountain guns, field guns, anti-aircraft machine guns, Type 38 rifles, pistols, telescopes, grenades, mines, and so on.
In March 1946, Yanji continued to serve a batch of quilts, and Kim Il Sung immediately asked the domestic factories to rush to make them, and in a short period of time, he sent 1,000 sets of finished military uniforms and cloth that could make 10,000 sets of military uniforms, as well as a train of medicines with leather. Kim Il Sung personally transported the supplies to the Yanji region of China and signed the delivery note. The largest batch of assistance from the Northeast Field Army was the 100,000 guns of various types that the Northeast Bureau sent chen yun and Xiao Jinguang to North Korea to request weapons assistance.
In 1946, the Shandong side also obtained 300 tons of explosives, 3 million detonators and 120 meters of fuses through its offices in North Korea. In the spring of 1947, he received 20 tons of explosives, 200 tons of nitric acid, 100 tons of acetone, and 15 pairs of rubber shoes. According to a report given by Zhu Lizhi, chief representative of the Northeast Military Office in Pyongyang, it can be concluded that during the three-year Liberation War, the DPRK successively aided more than 1,000 trainwws to the northeast.
In addition to material assistance, in the early days of the Liberation War, the Northeast Field Army was in a passive state, and many personnel and materials in and outside The Guanxi were transferred from Korea. In 1946, when Pan Shuoduan, commander of the 184th Division of the 60th Army of the Kuomintang Army, led the troops to revolt, the Kuomintang army led a heavy army to encircle and suppress, and this unit directly entered Korea by train, and finally crossed the border through Nanyang into Tumen, China. The now well-known China Resources Company, at that time, chartered two large Soviet cargo ships, and these two cargo ships were parked in the ports of North Korea, and they transported soybeans and other specialties from the northeast to Hong Kong and other places, and after selling them, they directly replaced them with electronic equipment, medicines, and some advanced weapons and other strategic materials urgently needed by the Northeast Field Army.
In addition, the DPRK also provided a lot of manpower support for the liberation of the northeast, and many people only knew that during the War to Resist US Aggression and Aid Korea, China sent a large number of troops to help the DPRK defend against foreign enemies. However, they did not know that after the outbreak of the Liberation War, Kim Il Sung called on his youth to join the Northeast Field Army as volunteers, and the Northeast Field Army formed these Korean youth into three Korean divisions, which were later sent back to Korea. It's just that now many people say that they are China's Korean teachers, in fact, before the founding of New China, there was no concept of Koreans at all, and the so-called Koreans also fled to China due to wars and other factors in the late Qing Dynasty, and settled in China. Therefore, the feeling that the blood of China and the DPRK is thicker than water is not only out of the need for propaganda, but has existed since ancient times.
