"Experts say new stimulus policies could add to firms' financial burden

China's corporate debt ratios have reached "dangerous" levels, according to leading economists.

Li Yang, vice-president of the Chinese Academy of Social Sciences, a top government think tank, has warned that further stimulus policies could add to the already heavy burden of corporate debt that is weighing on the world's second-largest economy.

China's corporate debt-to-GDP ratio stood at 107 percent in 2011, the highest in the world, Li said at a forum in Zhejiang province on Friday."
