SAN DIEGO (Border Report) — Two Mexican naval ships arrived in Havana on Wednesday loaded with more than 800 tons of humanitarian aid for residents on the island.

The vessels left earlier this week from the Mexican port of Veracruz.

Since last month, the U.S. has stopped oil shipments from Venezuela to Cuba, a move that has crippled the island’s economy and power grid.

President Trump has threatened to impose tariffs on any nation that provides Cuba with oil.

So far, Mexico has ignored the threat and possible sanctions.

It has promised to continue delivering oil and aid to the island as it negotiates an agreement with the White House.

Mexican President Claudia Sheinbaum said her country is doing it to avert a humanitarian crisis in Cuba.

The shipment that just arrived in Cuba contained powdered milk, meat products, cookies, beans, rice and hygiene products to Cuba along with bottled water.

Sheinbaum told reporters earlier this week that Mexico has said another shipment of 1,500 tons of aid is ready to be delivered.

Even before the latest sanctions imposed by the United States, Cuba was already in the midst of an economic collapse with high inflation, power outages and lack of food and medical supplies.
