South Korean activists today sprayed slogans on the outer walls of the US consulate in Hong Kong.
More than 100 farmers, workers and unionists sprayed "Down, down WTO" in red paint across the US consulate emblem and "No Bush" in black while throwing eggs at the building and waving banners.
They are protesting a World Trade Organization meeting of ministers intent on opening up farm markets.
Several shaved their heads while others beat drums, shouting that the United States had forced South Korea to buy its farm products, threatening their livelihoods.
Police stood by and watched at first, but waded into the crowd and began hustling people away from the building after they tried to pull down part of the "United States" sign.
The demonstrators marched to a nearby park, where many dispersed.
Not far away, around 100 protesters stormed the building housing the South Korean consulate after demonstrating outside.
Some broke past security guards and ran through the lobby into the elevators, attempting to reach the consulate on the fifth floor. More than 10 managed to reach the floor before building managers shut the elevators down.
It was not clear if they got inside the consular office.
After about six hours and several negotiating sessions with police, the protesters decided to leave. There were no arrests.
Many of the demonstrators were farmers bitterly opposed to the opening of the South Korean rice market to imports.
An estimated 10,000 anti-globalisation protesters, including some 2,000 South Koreans, who have a reputation as the most militant anti-globalisation group in Asia, have converged on Hong Kong for a meeting this week of world trade ministers.
Korean protesters clashed with riot police on the first two days of the WTO conference.
