Answer:
Corruption is a form of dishonesty or criminal offense undertaken by a person or organization entrusted with a position of authority, to acquire illicit benefit or abuse power for one's private gain. Corruption may include many activities including bribery and embezzlement, though it may also involve practices that are legal in many countries. Political corruption occurs when an office-holder or other governmental employee acts in an official capacity for personal gain. Corruption is most commonplace in kleptocracies, oligarchies, narco-states, and mafia states.
Corruption and crime are endemic sociological occurrences which appear with regular frequency in virtually all countries on a global scale in varying degree and proportion. Additionally, a global initiative like the United Nations Sustainable Development Goal 16 also has a target to substantially reduce corruption of all forms. Corruption can occur on different scales. Corruption ranges from small favors between a small number of people to corruption that affects the government on a large scale, and corruption that is so prevalent that it is part of the everyday structure of society, including corruption as one of the symptoms of organized crime.
Petty corruption occurs at a smaller scale and takes place at the implementation end of public services when public officials meet the public. For example, in many small places such as registration offices, police stations, state licensing boards, and many other private and government sectors.
Grand corruption is defined as corruption occurring at the highest levels of government in a way that requires significant subversion of the political, legal, and economic systems. Such corruption is commonly found in countries with authoritarian or dictatorial governments but also in those without adequate policing of corruption.
Some scholars argue that there is a negative duty of western governments to protect against systematic corruption of underdeveloped governments. Corruption has been a major issue in China, where society depends heavily on personal relationships. By the late 20th century that combined with the new lust for wealth, produced escalating corruption. Historian Keith Schoppa says that bribery was only one of the tools of Chinese corruption, which also included, "embezzlement, nepotism, smuggling, extortion, cronyism, kickbacks, deception, fraud, squandering public monies, illegal business transactions, stock manipulation, and real estate fraud."
