China and its trading partners this week began talks in Geneva that represent the final stage in Beijing’ s 15-year effort to join the World Trade Organization. The talks, expected to last a week, are aimed at clearing most of the remaining obstacles to China’ s member- ship. Officials said there is a lot of work to be done, but that they remain optimistic the problems can be worked out by the time WTO ministers meet in Qatar in November. Beijing has reached trade deals with all its partners, except Mexico.
