Walmart buys delivery app in Mexico and Central America

Walmart headquarters in the United States agreed to purchase Cornershop a grocery deliveries application in Mexico and Central America for $225 million.

Analysts say the purchase is one of several investments that Walmart is planning to compete with Amazon, the world's leading online retailer.

Cornershop, which also operates in Chile, will remain as an open platform for deliveries to a wide range of shops.
