After regaining independence after

, Germany pursued the diplomatic line of "the distance

should not be one millimeter closer than the distance

", so Germany Neither China nor

believe that Poland will do anything for them, and both regard Poland as their enemy. In addition, due to the failure of

negotiations with Britain and France and the rejection of

military assistance by Poland, the Soviet Union chose to unite with Germany and march into Poland in order to ensure its own interests and security. Basically the Soviet Union was hostile to Poland. The Republic of Poland (Polish: Rzeczpospolita Polska, English: The Republic of Poland, Chinese abbreviation: Poland), formerly known as Boliel, is a democratic republic of Poland consisting of 16 provinces. Poland is a country in Central Europe, bordering Ukraine and Belarus to the east, Lithuania and Russia to the northeast, Germany to the west, the Czech Republic and Slovakia to the south, and the Baltic Sea to the north. Poland has a distinct Eastern European feel. The most beautiful time in Poland is from May to September every year. The weather is warm and sunny. September is known as the beginning of "Polish Golden Autumn". July to September is the peak tourist season in Poland. Poland's important geographical location and topography have led to years of wars and disputes in history. Poland's territory has been changed repeatedly over the centuries. In recent years, Poland's status in the EU and on the international stage has also increased day by day. Since the restoration of independence on November 11, 1918 Since then, after 90 years of development and changes, especially in the early years of the 21st century, Poland's importance in Europe has attracted more and more attention. Poland is a member of the European Union, NATO, the United Nations, the Organization for Economic Co-operation and Development and the World Trade Organization. The disintegration of the Soviet Union (Russian: Распад СССР, English: Disintegration of the Soviet Union) On December 25, 1991, the Supreme Leader of the Soviet Union, Mikhail Gorbachev, announced his resignation and handed over state power to Russian President Yeltsin. That night, the Soviet flag slowly lowered from the Kremlin. The Union of Soviet Socialist Republics and the Soviet Union declared its disintegration. The international communist movement suffered a major setback, marking the end of the Cold War and the bipolar pattern. At this point, the Communist Party of the Soviet Union and the Supreme Soviet of the Soviet Union disbanded themselves. The Soviet Union no longer existed realistically and legally, and the Red Empire collapsed. The Russian Federation led by Yeltsin, who won the political struggle, inherited the Soviet Union's main comprehensive national power and international status. After the disintegration of the Soviet Union, the capital Moscow became the capital of the Russian Federation, the largest member country, and 15 countries were split off (the three East Slavic countries, the three Baltic countries, the five Central Asian countries, the three Transcaucasian countries, Moldova, etc.).
