China's Wen Jiabao arrives for trade talks in Germany

Chinese Premier Wen Jiabao has arrived in Berlin with a large trade delegation on the third and final leg of his European tour.
Economics is expected to dominate the agenda - China's trade with Germany dwarfs its trade with other European countries.
China wants more investment by German high-technology companies as it moves into more sophisticated markets.
But German firms do not want to lose know-how to future Chinese competition.
Both sides are now starting to understand how they can benefit from each other, with some German companies keen to manufacture in China and realising that this will involve some transfer of technology, but also learning what trade secrets to hold back.
China has one big card to play.
It has been increasing its holdings of bonds denominated in euros - in other words lending to eurozone governments.
Were that to change, the crisis in the eurozone would get worse.
