US signs treaty that regulates global arms trading

UNITED NATIONS (AP) — The United States has joined more than 90 other nations in signing a treaty that regulates global arms trading. But there's strong resistance in the U.S. Senate, which must ratify the accord.

The U.S. is the world's largest arms dealer, and its signing is seen as critical to the success of the Arms Trade Treaty. But many of the other top arms exporters have yet to sign.

Secretary of State John Kerry signed the pact Wednesday, on the sidelines of the U.N. General Assembly. He says it's a "significant step" in keeping the world safe.

Some senators who oppose the treaty contend it could infringe on Americans' rights to bear arms.

Kerry notes that the treaty does not regulate domestic weapons sales.
