Obama concern over Mexican drug-war policy
President Obama travels to Mexico this week amid signs that the relationship between the United States and its southern neighbor's new government faces a new period of uncertainty.
The uncertainty comes after years of unprecedented closeness forged by the deadly war against Mexican drug cartels.
The government of Mexican President Enrique Peña Nieto is said to be wary of the level of US involvement in security affairs that characterized the administration of his predecessor, Felipe Calderon.
