ONE TRADE DEAL AFTER ANOTHER:

More than 50 countries agreed on Friday to eliminate tariffs on a wide range of technology goods like medical devices, navigation equipment and advanced semiconductors in a trade agreement that should benefit American manufacturers, consumers and the global economy.

Signatories to the Information Technology Agreement, which covers 201 product categories, include the United States, the European Union, China, South Korea and other members of the World Trade Organization. International trade in those goods totals about $1.3 trillion a year, or about 7 percent of all trade.

Negotiators say this agreement is the most significant deal struck at the W.T.O. in almost two decades.
