Thank you.
Ambassador, you spoke in your comments about China's turning to green technology. I wonder if you could explore briefly the interest in China in that area, and the impetus. What exactly is motivating China to turn to that?
I understand that obviously there is a great deal of money to be made in the investments they've made in solar technology and wind technology—huge investments. However, they're also experiencing real concerns around climate and air quality, in particular in some of their major cities. Could you speak to that?
