BEIJING (Reuters) - Chinese officials said on Tuesday a Chinese-made blood thinner was not to blame for fatalities linked to the product, and accused U.S. drugmaker Baxter International Inc of obstructing the investigation into the cause of the problem. Baxter has recalled batches of the drug heparin that were found to be tainted with a similar but cheaper chemical that U.S. Food and Drug Administration officials say may have killed some 81 patients and caused allergic reactions in others.
