NEW YORK (TheStreet) -- Wal-Mart  (WMT - Get Report) is restarting its wholesale expansion in India, the world's second-biggest consumer market. 

Walmart opened its first wholesale store since 2012 on Wednesday.

The expansion is part of a plan to more than triple Walmart's presence in the country.

The company says it's on track to open 50 Best Price Modern Wholesale stores within the next four to five years, adding up to a total of 70 locations throughout India.

Walmart says it's shifting its focus to the B2B segment

The majority of the retailer's customers in India are owners of businesses themselves. They include the traditional mom-and-pop grocery stores that sell most of India's food.

The Best Price Modern Wholesale store stocks roughly 5,000 items, including fruits, vegetables, dry groceries, personal goods, home care items and other general merchandise.

However, some Wall Street observers think Walmart should focus on getting its U.S. business in order before expanding overseas.

In a recent note, Credit Suisse analysts said the retailer's international operations are dragging Wal-Mart down.

The firm wrote: "International division is consuming too much human capital as well as economic capital. We continue to think that the company will need to simplify and refocus on the core US business in order to sustain its industry leadership."

Bentonville, Ark.-based Walmart operates retail and other stores in various formats, including membership clubs.

The company operates through three business segments which consists of Walmart U.S., Walmart International and Sam's Club.

Shares of Walmart Stores were up slightly Wednesday shortly before trading ended. The stock has fallen more than 16% so far this year, and has lost nearly 4% over the past year.
