With widespread corruption in many Asian countries, Singapore and Hong Kong SAR have proved exceptions: their governments’ strong political will and reliance on single “Type A” anticorruption agencies (ACAs) have effectively and impartially enforced anticorruption laws. By contrast, the governments in China, India, and the Philippines have failed to minimize corruption due to weak political will and reliance on multiple ineffective and poorly resourced “Type B” ACAs. This essay draws on the experiences of these five countries to identify four lessons for policy-makers to enhance the effectiveness of their ACAs.
