CARACAS Aug. 12 (Xinhua) -- Venezuela and Guatemala have signed an energy agreement to guarantee Guatemala a daily supply of 20,000 barrels of crude and refined products, the Venezuelan foreign ministry said Wednesday.

    The agreement with Guatemala guarantees the supply of crude oil, refined products and liquefied natural gas from Venezuela for even 20,000 barrels daily.

    The agreement is part of the Petrocaribe alliance launched by Venezuelan president Hugo Chavez in June 2005, which allows Caribbean nations to buy 185,000 barrels of oil daily.

    The Petrocaribe is formed by 18 countries. Guatemala joined the bloc in 2008 in Maracaibo city, western Venezuela.
