China's online grocery giant Yihaodian launched a "virtual store" focusing on baby products on Monday, the first of its kind on the Chinese mainland. Customers will be able to order diapers and baby formula with a special application on their mobile phones.

"With the increasing number of urban white-collar parents who don't have much time to shop in stores, mobile e-commence can help them shop for baby products in a few minutes on their way to work," said Yihaodian marketing VP Pan Qi.

The yihaodian.com virtual store mobile app is currently available in Chinese for the iOS and Android operating systems.

Earlier this year, US retail giant Walmart increased its stake in Yihaodian to 51 percent in order to boost its online presence in China.

Walmart did not disclose financial details of the partnership with Yihaodian, but it already held a minority stake in the business.

Yihaodian sales rose to 2.7 billion yuan ($429 million) in 2011, from 805 million yuan in 2010.
