The company's first store outside the United States was a Sam's Club in Mexico City, which opened in 1991, according to its website.
Walmart has struggled to expand into markets abroad for years. Competing discount chains across the globe that are able to offer shoppers better prices and service shoppers with unique needs pose a threat that the company doesn't quite face in the US.
After trying and failing at putting its own name on stores in certain countries, the biggest retailer in America - and the world - decided to start acquiring or investing in existing warehouses and wholesalers to keep its hand in the international business game.
Some locations, like Brazil and China, continue to be challenging for Walmart.

On February 1, 2018, the retail behemoth changed its corporate name from Wal-Mart Stores Inc. to Walmart Inc. The change in name reflected the company's shift away from brick and mortar and toward other ways of selling, like with its online business.
In addition to expanding its assortment on Walmart.com, the retailer has acquired a number of digital-focused brands since 2010.
On Jet.com — the e-commerce site Walmart bought for $3.3 billion in 2016 — shoppers get an extremely localized and personalized experience.
Shoppers can order electronics, shoes, groceries, toys, and a toothbrush all in one package — kind of like what they'd be able to get from a regular in-person trip to Walmart.
Walmart has its hand in retail and e-commerce in 27 countries, with more than 11,200 retail units working under 55 banners worldwide.
The global expansion hasn't come easy for the world's biggest retailer, though.
The initial effort put the Walmart name on stores around the globe, but it proved rather difficult for the company to correctly identify the needs of its non-American consumers.
After multiple failed attempts to expand the Walmart brand into Europe, the company began to change its approach to international growth.
It became less concerned with having the Walmart name on every store and instead focused on acquiring pre-existing discount stores.

Some countries around the world do have stores that bear the Walmart and Sam's Club names.
But Walmart is often behind stores with other names. In the UK, Walmart has owned the collection of Asda stores since 1999. In 2018, Walmart announced a plan to merge Asda with Sainsbury's to create a British retail giant.

Walmart first opened in China in 1996. It has since expanded across the country — here is one store in Beijing's Chaoyang district.
It has been a struggle for the company to hold onto this "crucial" market as it vies for consumers' trust and belief in the stores as an authentic shopping option.
One Business Insider reporter, Harrison Jacobs, went inside the Beijing Walmart store to see what it's like to shop there.
He was able to see the differences between the China-based location and the ones in the US. For starters, there are customer lockers when you first walk in the door.
On these shelves, he found high-end cosmetics right next to discount toilet paper, and there were lots and lots of pre-packaged foods.
Shelves are stocked with a wide range of items in an effort to cater to local shoppers. In Beijing, it's common for apartments not to feature a stove, so the Beijing Walmart sells a variety of hot plates.
There are also tanks of live fish ...
... turtles and frogs ...
... and a selection of meat like chicken feet.
While the hypermarkets, supercenters, and membership-based stores around the world may fall under different brand names ...
... they all attempt to give local customers the best prices for the goods they want.
And they do that by selling under names the consumers are used to seeing.
The company also promises to give back to these communities around the world through the Walmart Foundation.
According to the company, all of this expansion allows it to employ around 2.2 million people around the world.
