Updated at 3.14pm: Protesters from South Korea - many of them farmers who say they have been negatively portrayed in Hong Kong's media - warn they might intensify their protests against the World Trade Organisation.
Protest organisers on Monday vowed to take 'affirmative action' if the Hong Kong government violated their freedom of speech - but they did not elaborate on what type of protests they would launch.
Ju Jay-jun, the general co-ordinator of the Korean Struggle Mission - an umbrella group for the 1,500-strong Korean delegation - said they would mobilise as many people as they could for demonstrations.
The WTO ministerial meeting begins on Tuesday.
Yang Kyeong-kyoo, vice-president of the Interim Committee of the Korean Confederation of Trade Unions, said they had planned a strategy for their upcoming protests. 'But I can't clarify [them] now,' Mr Yang said on Monday.
He said he could not rule out the possibility of members committing suicide. In a notorious incident, a Korean farmer, Lee Kyung-hae, killed himself while protesting outside the WTO meeting in Cancun, Mexico, in 2003. Other Korean farmers have committed suicide in more recent protests.
