Differences in prosecution and punishment for corruption in various countries: Japan emphasizes "integrity" very strongly, with no monetary threshold; even small amounts will lead to prosecution, and the social consequences are severe: resignation, end of political career. The United States has no monetary threshold, distinguishes between bribery and illegal remuneration; even small amounts can prove exchange of benefits and lead to conviction, with a maximum of 15 years. In Singapore, a "zero tolerance" approach is adopted, with no monetary threshold; even dozens of Singapore dollars can lead to prosecution, and the burden of proof is relatively low. China, which does not take a penny from its people, convicts those with unexplained sources of assets starting at 3 million RMB; the difficulty of evidence depends on political stance.
