China and Taiwan will this week hold historic talks aimed at building trust following decades of angry rhetoric and military tensions that made their relationship one of the world's potential flashpoints.  The four days of meetings in Beijing starting on Wednesday will be the first direct dialogue between the rivals in over a decade and have come about thanks to a dramatic rapprochement between the long-time rivals in recent months. Establishing permanent direct flights between China and Taiwan and allowing more mainland Chinese tourists to visit the island will be the main topics on the agenda. However analysts from China and Taiwan agreed that, with mutual distrust and suspicion so entrenched, this week's events were only the first step in a very long march towards a permanent thaw in ties.
