Allen & Overy has advised the government of Vietnam on its latest issuance of sovereign debt worth $1 billion.

The Southeast Asian country is using the deal to swap out debt from previous issuances in 2005 and 2010 that raised $750 million and $1 billion, respectively, according to Reuters. The newswire said Vietnam needs high levels of funding to accommodate its economic growth, which is expected to reach 5.8 percent this year and 6.2 percent in 2015.
