Let me bring in our correspondent Wang Tongxuan for more details on their meeting. Welcome.

Q1. A lot of issues on the table, Tongxuan.  But what's been the focus of their talks?  What have they agreed on?

Q2. Chancellor Merkel's visit is part of the high-level exchange mechanism between China and Germany.  It was established five years ago to allow the two countries to deepen their cooperation.  Can you explain to us how this mechanism works?
