WASHINGTON (AP) _ Dozens of countries have agreed to abolish duties on more than 200 technology products _ from advanced computer chips to GPS devices, printer cartridges and video-game consoles.

The agreement announced Friday marks the World Trade Organization’s first tariff-killing deal in 18 years.

The deal is an expansion of the 1997 Information Technology Agreement, which includes 80 WTO member countries. The updated accord covers products that generate $1 trillion in annual global revenue, including $100 billion a year for American companies.

That worldwide total is equal to global trade in iron, steel, textiles and clothing combined, according to the WTO.
