German Chancellor Angela Merkel has welcomed Chinese Premier Li Keqiang to her country retreat north of Berlin.
It was smiles all round after the signing of a range of bilateral business agreements.
But a trade row is brewing with the EU.
Chinese officials will meet for informal talks with the European Commission on Monday to try and defuse a dispute over solar panels and wireless equipment.
China denies EU claims that it prices its solar panels and mobile telecom devices too cheaply and dumps them in Europe to corner the market.
But Brussels is considering imposing punitive import duties on solar panels from China.
This comes after the US levied its own duties last year, a decision opposed by Beijing.
The EU is China’s most important trading partner while for the EU, China second only to the US.
