In an article about the increasing diplomatic pressure and military build-up in the melting Arctic Circle, this is the extent of the response that Reuters got from a top U.S. official:

"We will seek cooperative strategies," U.S. Deputy Secretary of State Jim Steinberg told Reuters during a meeting of Arctic Council foreign ministers in Tromsoe, Norway.

I can't help thinking the obvious: that signing the Law of the Sea treaty is one of the easiest "cooperative strategies" that the United States could already be pursuing. They wouldn't even have to "seek" it; it's right there on the table, open for Senate ratification.
