China signs deal with Samoa as Australia vows Pacific Islands plan

China's foreign minister signed a deal with Samoa on Saturday to strengthen diplomatic relations, while Australia's new leader said he had a "comprehensive plan" for the Pacific, as Beijing and Canberra continued rival campaigns to woo the region.

China is building on a security pact it recently signed with Solomon Islands, which has alarmed the United States and its allies such as Australia as they fear a stepped-up military presence by Beijing. Australia's new centre-left government has made the Pacific Islands an early diplomatic priority.

Prime Minister Anthony Albanese, sworn in on Monday, said on Saturday his Labor government's plan includes a defence training school, support for maritime security, a boost in aid and re-engaging the region on climate change.
