The Ministry of Foreign Affairs and External Trade (MFAET) explains the Vienna Convention on Diplomatic Relations.
This is in response to the recent incident where the address on a package was alleged to be mailed from the Taiwan’s Ministry of Foreign Affairs to an individual in Solomon Islands.
The MFAET wishes to clarify that Solomon Islands has domesticated the Vienna Convention on Diplomatic Relations within its laws, under the First Schedule of Solomon Islands Diplomatic Privileges and Immunities Act.
Under Article 27 of the Vienna Convention on Diplomatic Relations, the host country must permit and protect free communication between the diplomats of the mission and their home country.
A diplomatic bag, also known as a diplomatic pouch, is a container with certain legal protections used for carrying official correspondence or other items between a diplomatic mission and its home government or other diplomatic, consular, or otherwise official entity.
Additionally, a diplomatic bag usually has some form of lock and/or tamper-evident seal attached to it in order to deter or detect interference by unauthorized third parties.
The most important point is that as long as it is externally marked to show its status, the “bag” has diplomatic immunity from search or seizure, as codified in article 27 of the 1961 Vienna Convention on Diplomatic Relations.
It may only contain articles intended for official use. It is often escorted by a diplomatic courier, who is similarly immune from arrest and detention.
MFAET strongly informs that the use of diplomatic pouch can only be done between states.
Any reason as to why Taiwan or any entity that transmitted the boxes decided to override the diplomatic pouch privilege is only reasons known to them only.
