I’m not sure it is a separate. Have you followed the tracking at NASA?
French President Nicolas Sarkozy, is here on vacation and will be at the conference. It was reported in June that Sarkozy would travel at the invitation of U.S. President George W. Bush to New York and Washington at the end of September.
Just an fyi. :)
I'm not sure what you mean, and no, I don't regularly track dust storms. However, for more on the Asian brown cloud, check the links below:

Checking the Wikipedia links, there is some media (and Wikipedia) confusion of the two. The term "Asian brown cloud" primarily refers to the smoke/pollutant aerosol haze from India and China that is usually found over the Indian Ocean, Indonesia and the related seas, the Chinese mainland, and extending over Taiwan, Japan, and Korea. Asian dust storms are usually Gobi and Taklimakan (Mongolia) storms that can travel over Japan, Korea, Siberia, and the Pacific Ocean. Pollution from the Asian brown cloud can get mixed with the dust storms, but they are mostly separate phenomena.
