Debevoise & Plimpton has advised U.S. investment company KKR on the formation of a $6.4 billion fund that focuses on infrastructure and energy-related investments across the fast-growing Asia Pacific region.

Reuters reported KKR as saying that it is the largest pan-regional infrastructure fund to have been raised for the Asia-Pacific.

"As Asia accounts for more than 60 percent of global growth, driven by rising domestic consumption and productivity, rapid urbanisation, and an enormous emerging middle class, the need for new infrastructure and sustainable energy sources will continue to accelerate," said Hardik Shah, a partner in KKR's infrastructure team based in Mumbai, in a statement.

The Debevoise team was led by partners Andrew Ford and Stephen Jordan.
