UNITED NATIONS, Oct 11 (Reuters) - The U.N. Security Council agreed on Thursday on a statement deploring the Myanmar government's crushing of pro-democracy demonstrations, a Western diplomat said. Western countries and China had resolved differences over the wording of the statement, first drafted by the United States, Britain and France on Friday, the diplomat told Reuters on condition he was not identified. The statement was expected to be issued shortly, he added. It would be the first time the council had taken any action over Myanmar and mark a shift of position by China, which had previously used its veto to stop the 15-nation body voicing criticism of Myanmar's ruling military junta.
