Taiwan’s diplomatic footprint in the Pacific shrank further on July 16 when Papua New Guinea abruptly announced the closure of Taiwan’s Economic and Cultural Office in Port Moresby.
“The physical presence of Chinese Taipei will no longer be recognized or required within the jurisdiction of Papua New Guinea,” Foreign Minister Justin Tkatchenko said in a statement that gave no warning and offered no negotiation.
China welcomed the move. Foreign Ministry spokesperson Lin Jian praised the decision, signaling Beijing’s continuing success in peeling away Taiwan’s remaining partners.
Taiwan’s Ministry of Foreign Affairs rejected the unilateral closure, announced a reassessment of bilateral cooperation and economic exchanges, and briefed like-minded partners. But the language of protest cannot mask the trend: Taiwan’s diplomatic space is contracting, and the Pacific is ground zero for the squeeze.
The closure matters beyond symbolism. PNG supplies roughly 1.2 million tonnes of LNG per year to Taiwan, about 6 percent of Taiwan’s total LNG imports. Combined with Australian supplies, roughly 44 percent of Taiwan’s LNG comes from south of the equator, traveling through the Coral Sea, the western Pacific, and the Philippine Sea. This route avoids the Strait of Hormuz, the Malacca Strait, and the South China Sea, making it one of Taiwan’s most resilient energy corridors.
The loss of a diplomatic office does not directly threaten existing commercial LNG contracts. But it means Taipei loses the ability to maintain government-to-government contacts, support commercial relationships, coordinate during emergencies, or protect its interests in a strategically located Pacific country. When the next crisis comes, rebuilding those connections will be far harder than protecting them today.
China’s footprint in PNG is expanding rapidly. Chinese-linked dual-use projects include the Lae Port, multiple airport upgrades, a government data center, the national broadband transmission network, the Kumul submarine cable, and power transmission infrastructure. These projects create long-term technical dependencies and logistical advantages for Beijing.
The closure also has implications for the broader Pacific sea lines of communication. The PNG-Taiwan shipping route is part of a network linking the Coral Sea, the Bismarck and Solomon Seas, the Philippine Sea, and the approaches to the first and second island chains. It serves as an alternative corridor for both commercial shipping and military logistics in a Taiwan contingency scenario.
Taiwan now has formal diplomatic relations with just 12 countries. Its informal offices, like the one in Port Moresby, have become the front line of China’s campaign to isolate the island. PNG’s decision shows how quickly even those footholds can be taken away.
