The Chinese government has recently made available its 30 meter resolution global landcover by donating this dataset to the UN.  This dataset is available currently for only the years 2000 and 2010. These global landcover maps have been developed from USA’s Landsat TM/ETM+ and China’s HJ-1A/1B satellite imagery. The overall accuracy of the 2010 global landcover map seems quite reasonable, with an accuracy of 80.33 % and a Kappa value of 0.75. The dataset is accessible here, with more details here.  The web portal also has a nifty option of geocoded screen-split, which allows the user to visually look at changes in global landcover between 2000 and 2010.
