Dear President Xi and President Obama,
You will both have received many public and private letters
of advice prior to your meeting on Friday and Saturday in California. They will
urge you to take up specific issues ranging from military and trade concerns to
human rights. That diversity of concern is an indicator of how complex the
relationships between your two countries are. They lend themselves to no easy
solutions, and it is doubtful there will be immediate, radical change when you and
your teams conclude the talks.
