"Well, we'll see. To say the least, we will judge according to actions, not words."Among the irritants, Lavrov cited the U.S. Magnitsky list of Russian officials tied to the 2009 death in custody of whistle-blowing lawyer Sergei Magnitsky.On April 12, Washingtonon 16 officials connected with Magnitsky's death and two others accused of other human rights abuses.with its own sanctions againstit says have abused the rights of Russian citizens.Lavrov also mentioned the deaths of Russian children adopted by U.S. citizens. The death in January of three-year-old Max Shatto, born Maksim Kuzmin, in Texas sparked a bilateral crisis after Russian officials accused his adoptive parents of "murder."Russia suspended the adoption of Russian children by U.S. citizens in January following several similar cases. Americans have adopted more than 60,000 Russian children since the collapse of the Soviet Union.
