Report: Abandoned Chemical Weapons in China SOCIAL AND ENVIRONMENTAL ASPECTS OF ABANDONED CHEMICAL WEAPONS IN CHINA by Hongmei Deng and Peter O’Meara Evans Dr. Hongmei Deng was a visiting Research Fellow at the Center for Nonproliferation Studies (CNS) of the Monterey Institute of International Studies from January to May 1997. She is an associate professor of chemistry at the Center of Analysis and Measurement of Fudan University in Shanghai, China, where she works with Fudan’s Arms Control and Regional Security Program. Her research interests include the Chemical Weapons Convention and its implementation in China. Peter O’Meara Evans is a Research Associate at CNS. In 1996, he worked for six months in the Chemical Demilitarization Branch of the Provisional Technical Secretariat of the Organization for the Prohibition of Chemical Weapons. rom 1937 to 1945, Japan employed chemical vides, “Each State Party, during the implementation of weapons against China and then abandoned large its obligations under this Convention, shall assign the Fnumbers of unused chemical munitions on Chi- highest priority to ensuring the safety of people and to nese soil.
