World beverage leader Coca-Cola announced the launch Monday of its largest plant in Russia in a move aimed at countering the growing influence in the region of its US rival PepsiCo. The shiny new $120 million plant in the southern city of Rostov-on-Don will supply fizzy drinks to the tens of thousands of fans who converge on the nearby city of Sochi for the 2014 Winter Olympic Games. "Today's plant opening once again highlights our intention to put long-term investments in place within the Russian economy," Coca-Cola chief executive Muhtar Kent said at the opening ceremony. The company said it planned to invest about $3 billion in the Russian economy in the next three years as its seeks to counter PepsiCo's growing influence in the ex-Soviet states. PepsiCo earlier this years acquired a two-thirds stake in Russia's second-largest food and beverage company Wimm-Bill-Dann for $3.8 billion. The investment by Coca-Cola's main rival was PepsiCo's largest outside the United States and underscored its commitment to a market it first penetrated in 1973. The stiff competition folds nicely into the Russian government's plans to boost stalling regional growth. Russia has sought to attract foreign direct investments as it tries to kick-start a modernisation drive intended to wean the country off its dependence on energy revenues. PepsiCo has worked its way into the Wimm-Bill-Dann deal by investing some $3 billion in Russia over the past decade. It plans to pour another billion dollars into Wimm-Bill-Dann by the end of the year. Coca-Cola said its investments in Rostov will be made between next year and 2016. Local officials have highlighted the plant as an example of the investments generated by the ability of Prime Minister Vladimir Putin -- expected to return to the presidency next year -- to bring the Olympic Games to Russia against long odds. "The construction of this new plant demonstrates that the Sochi 2014 Winter Olympic and Paralympic Games have become a catalyst for economic development in southern Russia," said the Games' organising committee chief Dmitry Chernyshenko.
