What is the bilateral relationship between Mexico and the United States?

The development of Mexico-US relations has gone through four stages. After Calderon took office as the president of Mexico, there have been some new changes and adjustments in Mexico-US relations. Calderon's policy towards the United States has become more pragmatic and rational, and he has emphasized Mexico's independence and autonomy. Bush mainly adopted conciliatory measures towards Mexico and showed goodwill on some major issues facing the two countries. The main theme of Mexico-U.S. relations in the future will still be cooperation. However, there are still many differences and contradictions between Mexico and the United States on issues such as immigration, trade, anti-drugs, and how to deal with regional security, which have brought difficulties to the development of bilateral relations.
