Sen. Erwin Tulfo filed Senate Resolution No. 739 on Monday, aimed squarely at the Chinese ambassador's recent remarks. The resolution urges the Department of Foreign Affairs to recommend declaring Ambassador Jing Quan persona non grata. It responds to Jing's statement that China 'may easily win' if it chose force in a confrontation over the disputed waters. A persona non grata designation would mean the ambassador is no longer welcome and could be ordered to leave. Manila has weighed such a step against China before without following through, so the request carries real symbolic weight. The filing still shifts pressure onto the executive branch, which decides what recommendation the DFA makes.
