The five-year action plan added China would "provide assistance in laboratory construction use for fingerprints testing, forensic autopsy, drugs, electronic and digital forensics".
The sums of money mentioned in the agreement were not large - US$200,000 (NZ$300,000) - and would be provided by China to the Secretariat of Pacific Regional Environment Programme (SREP) in 2022 to continue to provide aid. China would also provide US$1.08 million (NZ$1.6m) to the Pacific Islands Forum this year, along with other aid.
In the context of the Pacific, however, those sums are relatively large. The Pacific Islands Forum received about NZ$4.4m in member contributions in 2020, a significant portion of its NZ$14.3m annual income.
Guangdong also promised about NZ$11.5m in "livelihood assistance".
The agreement reiterated a target of doubling bilateral trade volume by 2025 from 2018 levels, and added an ambition for greater investment from Chinese companies in the Pacific.
The agreement promised greater cultural cooperation, including institutions that would promote cultural cooperation in the Pacific. China also promised a number of scholarships: 100 "training opportunities" for professionals, 20 scholarships from Tianjin municipality, and 2500 other scholarships from 2022-2025.
The agreement has some strings.
The communique opened by promising to reaffirm that "all countries, regardless of their size, strength and wealth, are equals".
But this is balanced by the islands reaffirming they "firmly abide by the one-China principle" and stressing "the importance of upholding the principle of non-interference of internal affairs in international relations".
Put simply, nations that sign-up will have to toe China's line on the issue of Taiwan.
The document is already raising eyebrows. It has been leaked extensively, indicating a level of dissatisfaction.
In a letter to 21 Pacific leaders, reported by Reuters, Federated States of Micronesia President David Panuelo said his nation would argue the "pre-determined joint communique" should be rejected, because he fears it could spark a new "Cold War" between China and the West.
China's growing presence in the Pacific has been alluded to as a concern by defence officials, who wrote in the 2021 Defence Assessment that the "establishment of a military base or dual-use facility in the Pacific by a state that does not share New Zealand's values and security interests" was a key risk for New Zealand.
China's Foreign Minister Wang Yi is on an eight-stop tour of the Pacific.
Prime Minister Jacinda Ardern, speaking during her trip to the United States, said the Pacific was a "contested region".
"We want cooperation in areas where we have shared concern, like climate adaptation and mitigation," she said.
"We want quality investment in infrastructure. We don't want militarisation. We don't want an escalation in tension. We want peace and stability."
