What are China's Interests in the Arctic?

Question

I am aware that the Arctic is full of natural resources and the USA (Alaska), Russia, Canada, Denmark, and Norway have each of their EEZ (Exclusive Economic Zone) according to the United Convention on the Law of the Sea. I am not aware that China is supposed to have an EEZ in the mentioned region, as they're not in the region but I've come across videos and digital Newspapers that China is interested in application in the region and I'd like to know what they've done so far (Polar Silk Road)! Apart from gaining natural resources, what other interests does China have in the Arctic?

According to Wikipedia:

In January 2018, China released its official Arctic Policy paper.2 The document draws a picture of how China views the economic possibilities the region offers. With this, China has vowed to actively participate in Arctic affairs as a "Near-Arctic State" and a major stakeholder in the Arctic.1 China has also focused on developing military projection capabilities that would extend into the Arctic region

According to a briefing by the European Parliamentary Research Service:

China's white paper on its Arctic policy of 26 January 2018 confirms that the region has significantly moved up China's foreign policy agenda during President Xi Jinping's first term of office (2013-2018).1 To legitimise China's growing role and interest in the Arctic despite its short Arctic history and lack of sovereign rights, the paper highlights China's scientific research on the Arctic since the 1990s and its increasing engagement in Arctic governance since it was admitted in 2013 as one of the current 13 observers to the Arctic Council.

Note: I am grateful for every contribution, whether short or long and I accept if the question is taken down if not met be Politics SE guidelines.

Answer 1

The Arctic provides a maritime passage for the nation of Russia in the form of the Northern Sea Route. Such a passage can help with economic development for Russia and provide a decent shipping route. Russia also conducts research on marine life, meteorology, and other topics in the Arctic, which it has been doing since the time of the Soviet Union. There may also be potential benefits for Russia to train members of its military and test weapons in the Arctic/icy regions & using "trefoil" bases for Arctic coastal defense.

Meanwhile, the United States also does research in the Arctic that is regulated by the US Arctic Research Commission. The United States and Denmark are looking to create some forms of infrastructure in the Arctic, including possible military and civilian airports near Greenland. The civilian airport would help for tourism. Meanwhile, the military airports in the Arctic will help both the Danish and US Airforce members conduct operations & training.

China sees the Arctic as a 'Polar Silk Road' with potential trade roads to expedite global shipping deliveries. China also spends more than the United States in terms of Arctic research, with the "Snow Dragon" icebreaker vessels being utilized for geoscientific research.

So, other than trade, the Arctic is important for research and new kinds of infrastructure for all three of these nations.
