Papua New Guinea: Closure of Taiwan representative office likely an attempt to placate China and maintain economic ties

Around 17 July, Papua New Guinea announced the immediate closure of Taiwan's representative office in Port Moresby. PNG maintained the decision was an administrative measure consistent with its long-standing One China policy and intended to strengthen relations with China. Taiwan said it had not been consulted, rejected the decision, stated its office would continue operating, and sought international support. China welcomed the move, while the United States said it reflected Beijing's efforts to isolate Taiwan. Between 20–23 July, Taiwan began reviewing its economic ties with PNG, including annual liquefied natural gas imports of approximately 1.2 million tonnes.

Assessment: The closure of Taiwan's representative office likely aims to reassure Beijing and continue economic cooperation, offsetting perceptions that the Pukpuk Treaty signals strategic alignment with Australia. Taiwan's lack of forewarning likely indicates it was a hasty decision by PNG leaders. Taiwan's review of LNG imports, refusal to close, and US criticism may lead PNG to reverse its decision and look for other avenues to placate China.
