you were talking about oil, which is an adjacent industry, which, 30 years ago, was more than 75 percent privatized but today is more than 90 percent owned by the public -- by the public sector and given what happened in the u.s. last year and also given that in china it's very typical for the government to force foreign players to have some sort of local joint venture, i was wondering how you think that might affect the dynamics of the industry going forward in the next few years.
