Hong Kong port strikers camp outside Li Ka-shing headquarters

HONG KONG (Reuters) - More than 200 striking dock workers camped outside the headquarters of Asia's richest man on Wednesday, pressing demands for a pay rise at a port operated by the tycoon that has disrupted traffic in the world's third-largest container port.

Unionists say they have had no pay increase for 10 years. Other demands have included improved hygiene facilities.
