South Korea's energy ministry said on Monday it had signed a 20-year liquefied natural gas (LNG) supply agreement with Qatar for the next 20 years starting in 2025.

　　South Korea's state-run Korea Gas Corp (036460.KS) will buy 2 million tonnes of LNG annually from Qatar Petroleum (QATPE.UL).

　　"This long-term contract is considered to have favourable contract conditions, which would help stabilise LNG supply as well as to significantly drop fees," the ministry said in a statement.

　　It did not provide financial details of the agreement.

　　The energy ministry added that KOGAS buys 9 million tonnes of LNG annually from Qatar through long-term contracts and a contract worth 4.9 million tonnes of LNG is expected to end in 2024.
