While the United States, Russia and several nations of the European Union have Arctic territory, China has none, and as a result, has been deploying its wealth and diplomatic clout to secure toeholds in the region.
“The Arctic has risen rapidly on China’s foreign policy agenda in the past two years,” said Linda Jakobson, East Asia program director at the Lowy Institute for International Policy in Sydney, Australia. So, she said, the Chinese are exploring “how they could get involved.” …
To ... improve relations with Arctic nations, its ministers visited Denmark, Sweden and Iceland this summer, offering lucrative trade deals. High-level diplomats have also visited Greenland, where Chinese companies are investing in a developing mining industry, with proposals to import Chinese work crews for construction.
One point the Times raises (which I hadn't thought of) is that last month's successful voyage through the Northwest Passage by China's icebreaker Snow Dragon was probably as much a test run as anything.
