DUBAI, United Arab Emirates -- American envoys say they are working with other nations on a proposal to drop all discussions on possible Internet regulations from a U.N. telecommunications conference in Dubai.

The U.S. is leading calls to reject possible new codes on the Net by the International Telecommunications Union, a 193-nation body making its first major oversight revisions in nearly 25 years. U.S. representatives held meetings Tuesday on the proposal to take all Internet-related discussions off the table.

The U.S. fears any U.N. Internet regulations could complicate commerce and be used by nations such as China and Russia to justify further cyber-crackdowns.

But the head of the U.N. group, Hamadoun Toure, insists the 11-day talks will not limit freedom of expression and will mostly seek ways to broaden Internet services to developing countries.
