Article XIII states that nothing in the Convention shall be interpreted as in any way limiting or detracting from the obligations assumed by any State under the Geneva Protocol of 1925 or the Biological Weapons Convention. The purpose of this Article is to establish, as a matter of international law, that the Convention does not undercut any State's obligations under the Geneva Protocol of 1925 or the Biological Weapons Convention. Note that paragraph 3 of Article XVI specifically provides that a State Party that withdraws from the Convention is still bound by any other treaty to which it is a party, in particular, the Geneva Protocol of 1925.
