Question: When did the Operation that seized the territories formally claimed by  Manchukuo began

<P0-S0> The Soviet invasion of Manchuria, also known as the Manchurian Strategic Offensive Operation ("Манчжурская стратегическая наступательная операция" , lit. <P0-S1>  "Manchzhurskaya Strategicheskaya Nastupatelnaya Operaciya") or simply the Manchurian Operation ("Маньчжурская операция"), began on 9 August 1945 with the Soviet invasion of the Japanese puppet state of Manchukuo. <P0-S2>  It was the last campaign of the Second World War, and the largest of the 1945 Soviet–Japanese War which resumed hostilities between the Union of Soviet Socialist Republics and the Empire of Japan after almost six years of peace. <P0-S3>  Soviet gains on the continent were Manchukuo, Mengjiang (Inner Mongolia) and northern Korea. <P0-S4>  The Soviet entry into the war and the defeat of the Kwantung Army was a significant factor in the Japanese government's decision to surrender unconditionally, as it made apparent the Soviet Union would no longer be willing to act as a third party in negotiating an end to hostilities on conditional terms. <SEP> <P1-S0> The Boy Scouts of Manchukuo ( "Mǎnzhōuguó Tóngzǐ Tuán Liánméng") was a Scouting association of Manchukuo. <P1-S1>  The Japanese military seized Manchuria in 1931, created the puppet government of Manchukuo in 1938, and controlled it until 1945. <P1-S2>  The Manchukuo government also set up Japanese-style Scouting in schools, which included para-military training. <SEP> <P2-S0> Manchukuo (: "Mǎnzhōuguó"literally: " State of Manchuria" ) was a puppet state in Northeast China and Inner Mongolia, which was governed under a form of constitutional monarchy. <P2-S1>  The area, collectively known as Manchuria by westerners and Japanese, was designated by China's erstwhile Qing Dynasty as the "homeland" of the ruling family's ethnic group, the Manchus. <P2-S2>  In 1931, the region was seized by Japan following the Mukden Incident and a pro-Japanese government was installed one year later with Puyi, the last Qing emperor, as the nominal regent and emperor. <P2-S3>  Manchukuo's government was abolished in 1945 after the defeat of Imperial Japan at the end of World War II. <P2-S4>  The territories formally claimed by the puppet state were first seized in the Soviet invasion of Manchuria in August 1945, and then formally transferred to Chinese administration in the following year. <SEP> <P3-S0> Operation Kugown relied on the media to inform the Guatemalan people on the extent to which communism had infiltrated Guatemala. <P3-S1>  This was largely derived from the documents seized by the PBHistory team. <P3-S2>  The analyzed documents were then translated into Spanish and distributed throughout Guatemala. <P3-S3>  Furthermore, the minister of propaganda in Guatemala held a press conference to discuss the findings of the Committee, which were actually the findings of the PBHistory team. <P3-S4>  Operation Kugown had three primary objectives. <P3-S5>  The first objective was to use the documents seized by the PBhistory in order to inform the Guatemalan people on the extent to which communism had infiltrated their country. <P3-S6>  The second objective was to publicize this to Latin America and the rest of the world. <P3-S7>  The last object was to solidify the position of the National Committee of Defense Against Communism (Comite de Defensa Nacional contra el Communismo) within the Guatemalan government. <P3-S8>  It was believed that with status the Committee could continue to track the movements of communists and communist activists and prevent further communist intervention within the region. <P3-S9>  Numerous press kits were realized to the local and international press. <P3-S10>  Understandably, the local press coverage was extensive. <P3-S11>  However, the International press failed to pick up many of the stories and the events in Guatemala were largely ignored. <P3-S12>  As indicated in the CIA summary of the operation, the "results of the third objective were considered eminently satisfactory. <P3-S13>  In all releases it was stressed that the committee not only was chasing communists, but was also looking for the documentation that reward valiant anti-communists. <P3-S14>  It was also emphasized that the Committee was working on the record of Red penetration for the benefit of future threats in the Americas, etc."
