World Trade Organization (WTO) members struck a deal to add more than 200 products to the list of goods covered by zero-tariff and duty-free trade.
In value terms, the deal cuts tariffs on 1 trillion US dollar worth of information technology (IT) products, which is equal to global trade in iron, steel, textiles and clothing combined.
The deal was agreed as part of need to update the 18-year old Information Technology Agreement (ITA) as it has become redundant.
Products added range from advanced computer chips to GPS devices, medical equipment, printer cartridges and video-game consoles.
