A　fast-changing　global　landscape　highlights　the　importance　of　understanding　spatial　price　dynamics　in　key　international　markets　such　as　China,　especially　in　the　era　of　COVID-19　pandemic　with　international　food　trade　and　food　system　experiencing　an　unprecedented　challenge.　Nowadays,　New　Zealand＇s　dominant　position　in　China＇s　dairy　import　market　is　being　challenged　by　European　Union　(EU)　dairy　exporters　leading　to　intensified　market　competition.　Using　monthly　export　data　of　skim　milk　powder　(SMP),　we　applied　threshold　cointegration　models　along　with　asymmetric　error　correction　models　to　examine　spatial　price　dynamics　and　price　transmissions　of　New　Zealand　and　Ireland　in　Chinese　and　global　markets.　We　found　that　New　Zealand＇s　export　prices　retain　their　leadership　position　in　China,　Ireland＇s　export　prices　are　well　more　aligned　with　those　in　international　markets.　In　terms　of　own-country　price　transmission,　Ireland＇s　relatively　symmetric　and　swift　adjustments　were　found　to　contrast　with　New　Zealand＇s　SMP　export　prices,　which　displayed　more　asymmetric　price　transmissions.
