Answer: the Mexican government broke off relations with the United States to protest the U.S. annexation of Texas.
Explanation:
When an effort at negotiation failed, the hard-driving Polk focused his efforts on subverting Mexican authority in California. Polk ordered several thousand U.S. troops under General Zachary Taylor to advance some 150 miles south of the Texas frontier and take up positions around Corpus Christi, near the Rio Grande in Texas. The U.S. troops were in territory that was doubly disputed: Mexico recognized neither the American annexation of Texas nor the Rio Grande boundary. Polk’s aggressive actions in Texas gained widespread support from rabid expansionists.
The last hope for peace died when an American official, sent to Mexico City to negotiate a settlement, gave up in March 1846. Mexican officials had allowed their pride to displace their prudence in refusing to acknowledge some of the legitimate issues between the two nations. Polk then resolved that he could achieve his expansionist purposes only by force. On May 9, he won cabinet approval of a war message to Congress. That evening the news arrived that Mexican troops had attacked U.S. soldiers north of the Rio Grande. Eleven Americans were killed, five wounded, and the remainder taken prisoner. Polk’s scheme to provoke an attack had worked.
Mexico opposed strongly to the annexation of Texas by the United States. They suspended all the diplomatic relations with the United States and also ordered that American Settlers be removed from CA and along with this they banned further American Immigration in Mexico.
Further Explanation:-
In the year 1845, Texas was annexed by the United States and from that moment on, it became the 28th State of the United States. Until 1836, Texas used to be part of Mexico but in 1836, there was a group of settlers living in Mexican Texas. They declared independence and called Texas as a new country named the Republic of Texas and from there on it remained as an independent country for nine years before the United States annexed Texas. There were political issues also which were raised within the United States as the question raised in this annexation was that Weather Texas will enter the United States as Slave State or Free State? And in the end, Texas became part of the United States as a Slave State. Because of this annexation, Tensions increased between the United States and Mexico and that brought to the start of Mexican-American war and the reason behind this war was that Mexico claimed that Nueces River was the southern border of Texas whereas the United States claimed that the border laid further south till Rio Grande River. As a sign to show Protest against Annexation, Mexicans banned American immigration and stopped all diplomatic relations with the United States.
