When the puppet state of Manchukuo was founded, only two countries in the world recognized it, one was Japan, and the other was killed by you. After Japan robbed our three eastern provinces, we immediately went to the League of Nations to file a complaint. In 1932, the League of Nations sent a delegation of experts to investigate, and found that it was indeed Japan that had violated China's sovereignty, so the report released by the mission proposed that Manchuria should be returned to China.
In 1933, the League of Nations convened a meeting and finally passed a resolution with 42 votes in favor, one against and one abstention, which did not recognize the legitimacy of the puppet state of Manchukuo and demanded the restoration of China's sovereignty over northeast China, which made Japan very dissatisfied with the announcement of its withdrawal from the League of Nations.

After the establishment of the puppet state of Manchukuo, the first to recognize it was of course Japan, and the other was a small country known to few people, El Salvador, so that many people in the League of Nations found it unbelievable, how dare such a small country oppose the entire international community?
How small is El Salvador? It became an independent state in 1841, only 20,000 square kilometers, and was ruled by a military man, Martinez. The country's declaration of recognition of the puppet state of Manchukuo on March 3, 1934, provoked the anger of the Nationalist government, accusing him of violating the Covenant of the League of Nations for not abiding by the Statutes of the League of Nations.
Of course, the puppet state of Manchukuo was grateful to El Salvador. In order to maintain this new friend, it is also a big price, they import a large number of coffee beans, the only specialty of the country, and even officials from the "Ministry of Foreign Affairs" of the puppet Manchukuo began to pack and sell them personally. According to the later recollection of a "diplomat" surnamed Song in the puppet state of Manchukuo, the people of the "Ministry of Foreign Affairs" at that time said that if other countries did the same, the "Ministry of Foreign Affairs" would become a sales department.
How did El Salvador recognize the puppet state of Manchukuo? It all started with an interview with a German journalist. Although Puyi, a puppet, founded the country, he still hoped that the world could recognize this country. As a result, the League of Nations conducted such a vote, leaving him in a very awkward position, and german journalists also found this problem.
Who knew that after the German reporter sent out the report on the interview with Puyi, El Salvador skipped to establish diplomatic relations with the puppet state of Manchukuo. The reason is that his president Martinez did not get international recognition after he came to power, especially the United States did not want to ignore him at all, which made El Salvador very angry, contrary to the choice of the League of Nations and the establishment of diplomatic relations between puppet Manchukuo.
It is funny enough to say that the establishment of diplomatic relations between this pseudo-Manchukuo and El Salvador is also funny enough. The two sides did not have diplomatic missions with each other, and the puppet Manchukuo did not go to El Salvador, nor did the Salvadorans go to the puppet Manchukuo. But in any case, when people admit it, they admit it.
Unlike El Salvador, which explicitly acknowledges the puppet state of Manchukuo, many other countries have adopted a tacit attitude. For example, Britain, the United States, France, Germany, Japan, and the Soviet Union all used the pretext of protecting their own diaspora, and although they did not establish diplomatic relations with the puppet state of Manchukuo, the consulate was still located in Harbin and continued to work there.
The first to adopt this method was the Soviet Union and later Poland. Even in October 1938, Poland received a delegation of envoys to Europe led by the puppet Manchukuo "Minister of Economy", and the two sides signed an agreement on economic reciprocity, which later allowed puppet Manchukuo to open a consulate in Poland.
Pseudo-Manchukuo is indeed a strange existence in the history of our country, in fact it should not exist at all, this is just a puppet regime supported by the Japanese planes and cannons, ridiculously this regime actually existed for a long time, and even many countries have openly and secretly acknowledged his existence, which shows how poor and weak China was at that time, and even its own country could not be protected.

Chi Zijian very much through the description of characters to describe a period of history, pseudo-Manchukuo tells the fate and experience of more than a hundred different characters, with a small view of the big let us understand the real pseudo-Manchukuo bit by bit, understand everything about the pseudo-regime, click on the link below to buy.
