Filipino protesters wearing masks painted with U.S. flags chant slogans in front of a police line near the Hong Kong Convention and Exhibition Centre, venue for the sixth World Trade Organization (WTO) Ministerial Conference December 16, 2005, during a protest denouncing the role of U.S. in WTO. The focus on agriculture in key WTO talks this week risks undermining the target of a wide-ranging deal to free up global commerce, a top EU trade official said on Friday. REUTERS/Bobby Yip
