Juxtaposed between anti-corruption initiatives and the principles of public international law pertaining to diplomatic immunity, this book critically examines the scope and limitations of diplomatic immunity in the fight against corruption. In a world where a very large number of States depend on richer nations for economic aid, it is inevitable that the old rule of non-interference in internal matters will be challenged. The traditional view is that Article 41(1) of the Vienna Convention on Diplomatic Relations 1961 prohibits diplomats from interfering in the internal affairs of the State to which they are accredited. Against this background, should diplomats from donor States be expected to keep quiet where the funds provided by the donor States to the recipient States are misused or otherwise corruptly spent?
