Anti-globalisation protesters have made their presence felt in Hong Kong ahead of a meeting there this week of the World Trade Organisation. Several thousand people have taken to the streets in what organisers say is just the first of many demonstrations planned over the next few days.Ministers from more than a hundred rich and poor countries are meeting for five days from this Tuesday. They are hoping to make progress towards an agreement aimed at lowering trade barriers and lifting millions of people out of poverty. Critics are not convinced that would be the result, however, claiming a deal would largely benefit richer nations at the expense of developing countries. Observers say two of the last three WTO ministerial conferences ended without agreement and a further setback could be fatal for the chances of negotiating a deal.
