China opened an embassy on a tiny, remote Pacific island during the pandemic. Here's why

Waves pummel the coast of Temwaiku, a village on the capitol island of South Tarawa, Kiribati.

(CNN)On a blue-sky day in May, as the coronavirus raged across the world, the Chinese flag was raised on a remote nation with a total population of 116,000, thousands of miles from Beijing.

The opening of a Chinese embassy on Kiribati, a nation of 33 atolls and reef islands in the central Pacific, might have seemed strange -- particularly during a pandemic. Just three other countries have embassies in the island state: Australia, New Zealand and Cuba.
Yet Kiribati is the site of growing geopolitical competition.
    Last September, it switched diplomatic recognition from Taipei to Beijing. China considers the self-governed island of Taiwan a breakaway province and has poached seven of its diplomatic allies since 2016.
      And this week, Kiribati's pro-Beijing President Taneti Maamau -- who oversaw the country's diplomatic switch -- won a closely watched election after campaigning for closer ties with China, defeating an opposition rival who was sympathetic to Taiwan.
      Kiribati is the latest example of Beijing's growing influence in the Pacific, which consists of a string of resource-rich islands that control vital waterways between Asia and America.
      The picturesque islands have long been aligned with the US, which has a large military presence, and allies such as Australia, the region's largest donor and security partner. But in recent years, many have forged closer ties with China due to Beijing's diplomatic and economic outreach -- creating a fault line for geopolitical tensions.
        Kiribati President Taneti Maamau attends a welcome ceremony at the Great Hall of the People in Beijing alongside Chinese President Xi Jinping in January.
        Now, as Canberra and Beijing pour aid into the region, the possibility of a travel bubble between the Pacific Islands and Australia has given the rivalry a new dimension.

        Deepening reach

        In 2006, then-Premier Wen Jiabao became the most senior Chinese official to visit the Pacific Islands. He pledged 3 billion yuan ($424 million) in concessional loans to invest in resource development, agriculture, fisheries and other key industries, signposting Beijing's interest in the region.
        Today, Beijing is its second-largest donor -- after only Australia, according to data compiled by the Lowy Institute, an Australian think tank.
        For the Pacific Islands, which have a combined GDP of about $33.77 billion -- less than 1% of China's total GDP -- China has been a crucial partner during the pandemic.
        Chinese health experts have given advice on how to fight the coronavirus over video conferences with their counterparts in the 10 Pacific Island countries sharing diplomatic relations with Beijing.
        In March, China announced the donation of $1.9 million in cash and medical supplies to the countries to help them combat Covid-19. It has also sent medical supplies, protective gear and test kits, according to statements from Chinese embassies in the region.
        Chinese medical teams are on the ground in nations including Samoa, helping local health authorities draft guidelines on how to control the coronavirus. In Fiji, specialized military vehicles have been provided.
        According to the World Health Organization, the Pacific has reported 312 cases and 7 deaths, the majority of which are in the US territory of Guam.
