Japan should join hands with the United States and other Arctic states in ongoing multilateral efforts to create a new shipping regime in the Arctic Ocean, a U.S. official said Thursday in Tokyo.

International cooperation is vital to ensure that shipping in the Arctic is "safe, secure and reliable," according to Mead Treadwell, chairman of the U.S. Arctic Research Commission, an advisory body to the president and Congress.

As a result of receding sea ice, caused by global warming, the Arctic is expected to open up for global shipping in the future. This will present strategic options for Japan's industry in light of shorter shipping routes from Japan to Europe via the Arctic Ocean, Treadwell said at a media conference in Tokyo.

The eight-nation Arctic Council, established in 1996 as a high-level intergovernmental forum to promote cooperation among Arctic states, is currently working on an Arctic marine shipping assessment, due to be completed in 2009, according to Treadwell.

The council's member states are the U.S., Russia, Canada, Denmark, Finland, Iceland, Sweden and Norway.

Trans-Arctic sea routes could be as important to global shipping as the Panama and Suez canals in the near future.

Aware of the strategic importance, China and South Korea have already joined the Arctic Council as observers and Treadwell recommended that Japan do likewise.

Aside from its potential for shipping, the Arctic is surfacing as a new battleground for energy resources. In August 2007, Russia stunned the world by planting its national flag in a titanium capsule on the seabed beneath the North Pole, causing other Arctic states — the U.S., Canada, Denmark and Norway — to scramble for a share of a potential new oil bonanza.
