THE HAGUE, Netherlands—25 February 2022 —National Authority and chemical industry representatives enhanced their knowledge and skills in preparing declarations and receiving and escorting OPCW inspections during an advanced training course held online from 7 to 25 February.

Timely and comprehensive declarations from National Authorities and chemical industry partners are essential in preventing the re-emergence of chemical weapons.”
