Why harmonisation of standards is hard
Launch library · evergreen read

Harmonising anti-corruption standards across countries sounds straightforward in principle but proves genuinely difficult in practice, since each country's legal system, enforcement capacity and political priorities differ considerably, and a standard that fits comfortably within one legal tradition may sit awkwardly within another built on different underlying assumptions.
Sovereignty concerns also complicate harmonisation, since countries are often reluctant to fully surrender control over how their own laws are written and enforced, even where broad agreement exists on the underlying goal. International standards therefore tend to set a shared floor rather than a single, identical rule applied uniformly everywhere.
Despite these genuine difficulties, gradual harmonisation continues, driven partly by international agreements and partly by the practical reality that companies and criminals alike increasingly operate across borders. A patchwork of inconsistent national standards simply creates more opportunity for wrongdoing to move toward whichever jurisdiction happens to enforce the weakest rules, even where existing rules already technically cover the situation.
