Texas warned residents for the third consecutive year not to travel to Mexico during the upcoming university spring break season, saying drug cartel violence and other criminal activity are a safety threat even in resort areas.
The advisory comes despite pleas from senior Mexican officials to target the travel warnings to specific areas where the threat of violence is greatest.
Mexican officials said that popular tourist areas such as Cancun and Cabo San Lucas are safe for Americans.
Drug violence has claimed an estimated 40,000 lives in Mexico since 2006.
"The Mexican government has made great strides battling the cartels, and we commend their continued commitment to making Mexico a safer place to live and visit," Texas Department of Public Safety Director Steve McCraw said. "However, drug cartel violence and other criminal activity represent a significant safety threat, even in some resort areas."
The number of Americans murdered in Mexico jumped from 35 in 2007 to 120 last year, McCraw said.
"Many crimes against Americans in Mexico go unpunished," he said.
Some crime in Mexico is directly related to cartel violence, and some is not, but rape is a serious problem in resort areas, said Tom Vinger, a spokesman for the Department.
"Some bars and nightclubs in resort cities like Cancun, Acapulco, Mazatlan, Cabo San Lucas and Tijuana can be havens for drug dealers and petty criminals," Vinger said.
Rodolfo Lopez Negrete, chief operating officer of Mexico's Tourism Board, met several Texas state officials and told them that the drug cartel violence is largely confined to isolated areas along the Rio Grande in northern Mexico, including the city of Juarez across from El Paso.
He urged the state to stress that the violence is not widespread, and that of the 22.7 million tourists who visited Mexico last year, almost none were in the vicinity of any type of violence.
"Those pockets where this violence is taking place are very well identified," Lopez Negrete said during his visit to Texas last week. "This is totally unrelated to tourism. This is not about attacking tourists."
Tuesday's announcement is a major blow for Mexico's economy. Tourism is Mexico's second-largest industry. About 60 percent of Mexico's visitors are American, and about one third of them are either Texans or people who pass through Texas.
"The bottom line is, we also have to look at the risk to American citizens, and we believe that risk is real, and the violence in Mexico is widespread and has actually grown from last year," Vinger said. "The nature of the violence is completely unpredictable, and I don't think you can say it is not going to happen in any specific place."
