Caning is a form of judicial corporal punishment in which a prisoner is officially whipped with a cane made of rattan. In a special report in 2010, Amnesty International estimates that as many as 10,000 people each year are subjected to caning in Malaysia and many of the punished are foreign nationals. Regarded by the organisation as a punishment that intentionally inflicts severe pain and trauma, in the opinion of that organisation it violates the absolute prohibition against torture and ill treatment under international law.
