HOUSTON (Reuters) - Mexico has come to the aid of the United States following Hurricane Harvey, sending Red Cross volunteers, food and supplies to a country whose president has proposed building a wall to keep the two neighbors apart.

Mexican volunteers wearing white vests labeled “Cruz Roja Mexicana” are distributing food and lending a sympathetic ear to some of the 1,800 storm refugees at the George R. Brown Convention Center, a temporary shelter.

A caravan of Mexican storm relief was due to be shipped north for victims of a storm that has killed some 60 people and left tens of thousands homeless since first coming ashore Aug. 25.

“We all know that there are some agreements and disagreements between governments, but for the Mexican Red Cross and the volunteers from the Mexican Red Cross, we are more than glad to be helpful and do some stuff to help people,” said Gustavo Santillan, one of the Mexican Red Cross volunteers.

Mexico was assembling relief for Harvey but the United States had not yet defined what help was required, a senior Mexican government official told Reuters.

Some 25 trailers were being prepared with rice, beans, coffee and chocolate along with 300 beds, nine generators, mobile kitchens, telecommunications equipment and personnel including paramedics and doctors, Mexico’s foreign ministry said.

“Mexico is ready to help those affected by Harvey,” Carlos Sada, Mexico’s deputy foreign minister for North America, told reporters in Mexico City on Tuesday. “It’s a demonstration of our neighborliness, a show of solidarity.”

One teary-eyed storm refugee in Houston said she was moved by the Mexican aid, especially considering the difference in wealth between the two countries, and it was wrong to try to shut out Mexicans.

“We don’t have time right now to put up borders and block Mexico, we need to come all of us together and work together,” said Bertha Navarette, 63, an evacuee from Pasadena, Texas.

U.S. President Donald Trump made building a border wall a central theme of his campaign, saying Mexico was sending “rapists” and drug dealers into the United States.

On Monday Trump scrapped a program that protects from deportation 800,000 people brought to the United States illegally as children, largely by parents who were Mexican nationals.

Thomas Oney, a homeless man at the George R. Brown Convention Center, said Harvey had shown that neighbors had to work together.

“I would hope that the talk about the border wall will stop,” said Oney, 41.

Mexico previously came to the aid of its northern neighbor in 2005, sending supplies and 195 people including medical staff following Hurricane Katrina. It marked the first time Mexican armed forces had been deployed in Texas since 1846.

The 33 Red Cross volunteers now in Texas are working in Houston, Corpus Christi and Beaumont at the request of the American Red Cross, said Marco Franco, deputy director for Mexican Red Cross Disaster Relief.
