He was in Beijing for the SARS outbreak in 2002/03 and for the Summer Olympics in 2008. That was also the year in which he reported on the intensifying unrest in Tibet and on the Sichuan earthquake, also reporting nine years later on its 2017 echo. He has interviewed many of the top Chinese leaders, such as Jiang Zemin, Zhu Rongji and Wen Jiabao. But he has also interviewed high-profile Chinese dissidents, including Bao Tong, Wang Dan and Wu'erkaixi.
