PepsiCo Inc. (PEP) and Pepsi Bottling Group Inc. (PBG) plan to invest $1 billion in Russia over three years to expand their manufacturing and distribution network in the country.

The investment will bring the cumulative investment in Russia by the two companies to over $4 billion, PepsiCo said in a statement Monday.

"This investment reflects very clearly our great confidence in Russia and our long-term commitment to this very important market," said PepsiCo Chairman and Chief Executive Officer Indra Nooyi.

In addition to the new beverage facility opening this week in Domodedovo, a new snacks manufacturing plant is expected to open later this year in the southern city of Azov. PepsiCo and PBG also are planning investments to build warehousing and distribution infrastructure for the Lebedyansky juice business.

PepsiCo also plans to continue its substantial investment in local agriculture.
