China, PNG Mark 50 Years of Diplomatic Ties

Chinese President Xi Jinping and Papua New Guinea Governor-General Bob Dadae exchanged congratulatory messages on Monday marking the 50th anniversary of the establishment of diplomatic relations between the two countries, with both leaders reaffirming a partnership that has deepened over five decades.

According to Xinhua, Xi described PNG as China’s “good friend, good partner and good brother” in the Pacific Island region and called for elevating their comprehensive strategic partnership. On the same day, Chinese Premier Li Qiang and PNG Prime Minister James Marape also exchanged congratulatory messages, pledging to advance high-quality Belt and Road cooperation.

A Half-Century of Ties

China and PNG established diplomatic relations in 1976. Since then, the relationship has grown into a comprehensive strategic partnership featuring mutual respect and common development. PNG holds a distinctive place in Beijing’s Pacific engagement: it was the first Pacific Island country to formalize Belt and Road cooperation with China, in 2018.

The economic ties are substantial. According to China Daily, PNG is China’s largest trading partner, largest investment destination and largest engineering contracting market among Pacific Island countries, while China is PNG’s second largest trading partner and largest export market.

Speaking at a reception in Beijing marking the anniversary, Yuan Mindao, vice-president of the Chinese People’s Association for Friendship with Foreign Countries, said the relationship’s foundation rests on equality. “Treating each other as equals is the greatest political foundation of our bilateral relations,” he said. “Fifty years is a milestone and, more importantly, a new starting point.”

People-to-People Roots

PNG’s ambassador to China, Thaddeus Kambanei, emphasized that the relationship predates the formal diplomatic arrangement. “More than a century ago, Chinese people began making their way to what is now Papua New Guinea,” he said. “This history reminds us that our relationship did not begin simply with an agreement between governments. It began with people meeting people.”

The ambassador highlighted PNG’s agricultural, fisheries, energy, mineral and tourism potential, describing China as “an important market and a leading investment and development partner.”

Both sides reiterated PNG’s adherence to the one-China principle. Dadae said PNG “firmly adheres to the one-China principle and looks forward to further deepening bilateral ties,” while Marape expressed appreciation for China’s “significant contributions to PNG’s economic and social development,” according to CGTN.

Balancing Act in the Pacific

The anniversary unfolds against a backdrop of intensifying competition for influence in the Pacific among China, Australia and the United States. PNG, which sits just north of Australia, has sought to balance growing Chinese economic ties with its traditional security relationship with its closest neighbor.

In October 2025, PNG and Australia signed a bilateral defense treaty unofficially named the “Pukpuk Treaty” after the Tok Pisin word for crocodile. The pact, Port Moresby’s first mutual defense agreement, allows up to 10,000 Papua New Guineans to join the Australian Defense Force and become eligible for Australian citizenship. As RFA reported, public opinion in PNG remains divided, with some welcoming employment opportunities and others warning the country could be drawn into a wider conflict.

China has said its Pacific engagement is not a geopolitical contest. In July 2026, Foreign Minister Wang Yi told PNG Foreign Minister Justin Tkatchenko that China “does not engage in geopolitical games or seek so-called ‘spheres of influence’” in the region, according to a Chinese Foreign Ministry readout. Tkatchenko confirmed PNG’s closure of the “Taipei Economic Office,” a decision Wang praised as consolidating the political foundation of bilateral relations.

Economic Opportunities and Concerns

China’s economic footprint in PNG has expanded through mining, infrastructure and diplomacy. During a three-day visit to Guangzhou in April 2026, Marape discussed partnerships in green energy, agriculture and special economic zones, and met investors in two mining projects: a potential gold and copper mine at Frieda River and an expansion of the Ramu Nickel Mine.

Those projects have drawn scrutiny. As RFA noted, the Ramu Nickel Mine has been criticized over environmental and labor standards, including a 2019 toxic waste spill that turned the ocean red and killed marine life. Critics warn the proposed Frieda River project could threaten the Sepik River ecosystem. China also granted PNG two parcels of land — in Beijing and Guangzhou — for diplomatic use.

Paul Barker, executive director of the PNG Institute of National Affairs, told RFA that investment should not be rushed. “Social, environmental and safety standards, equity, and ensuring local benefits must be prerequisites,” he said.

What to Watch

As both sides frame the anniversary as a new beginning, the coming years will test whether the partnership can deliver on its economic promises while managing the sensitivities of PNG’s parallel security ties with Australia. With the Belt and Road framework as the guiding template and a 2026 APEC cycle underway, China-PNG relations are likely to deepen — but the balancing act that defines PNG’s foreign policy is unlikely to disappear.
