(CNN)China could overtake Australia as the biggest donor to Pacific nations, but only if Beijing follows through on its promises of aid and support that are currently billions of dollars short of being realized.
Despite pledging a similar amount of money to Australia, concerns remain over how many Chinese commitments actually translate into reality, and the type of loans extended by Beijing to poorer nations.
According to a new project from Australia's Lowy Institute, a foreign policy think tank, China has pledged around $5.88 billion worth of aid to the Pacific since 2011, less than Australia's $6.72 billion. During the same period, the US committed $1.36 billion in aid to the Pacific.
The Lowy project was supported by Australian Aid, a government agency.
While Canberra is still the biggest player in the region, ongoing major spending under Belt and Road -- a colossal trade and investment project spanning 68 countries -- could see Beijing leapfrog it. In Papua New Guinea alone, China has pledged billions of dollars to build roads and other projects, some of which is not reflected in the Lowy data because the deals are in their early stages.
Whether Beijing's promises and highly publicized memorandums of understanding actually translate into anything on the ground is another matter however. During the 2011-2018 period, only around 21% of the money China pledged was actually spent, compared to 97% for Australia.
While China's aid commitments would see it overtake Australia in the near future, Jonathan Pryke, director of Lowy's Pacific Islands Program, was skeptical if actual spending would ever match Beijing's promises.
"China is talking a big game in terms of its commitments to the region and that's concentrated on one country, Papua New Guinea," he said. "I'm not convinced China will (overtake) Australia. We have a much broader, much deeper degree of engagement than China has."
Earlier this year, Australia's Minister for International Development and the Pacific Concetta Fierravanti-Wells accused Beijing of constructing "useless buildings" and roads that "(don't) go anywhere" while loading unsustainable debt onto poorer countries.
"It's really important for investment to be productive that it actually has some economic dividend," she said. "Burdensome debt can divert scarce public resources from more immediate needs such as health and education."
Canberra concern
Some in Australia have expressed concern Canberra is losing out in influence to Beijing, as successive conservative governments have cut aid spending to the Pacific as China has upped its involvement.
"China has played an increasing role in the Pacific while (Coalition governments) have increasingly abandoned the region, relentlessly hacking at our aid funding and seeing an $11 billion cut to the development budget," opposition Labor senator Penny Wong said in January. "Pacific island neighbors have felt the impact of these cuts."
Pryke said that "if there's an upside to Chinese engagement in the Pacific, other than bringing resources for development, it's forcing Australians and New Zealanders to up their game."
Australia has become increasingly gripped by concerns over Chinese influence in the country, and relations between Beijing and Canberra have deteriorated around the passage of an anti-foreign influence laws seen as targeting China.
A series of angry editorials and opinion pieces in Chinese state media when the laws were first introduced labeled them "disgraceful" and "absurd,"
