Foreign investors may take legal action against Vietnam if it does not fully pay electricity tariffs agreed with multiple wind and solar projects, according to a document signed by five chambers of commerce. The issue arose after lengthy negotiations with affected investors, who run projects with a combined capacity of 12 gigawatts. The chambers from the European Union, Britain, Japan, South Korea and Thailand have sent a joint letter to the government requesting an amicable resolution. The high tariffs increased losses for state-owned power utility ⁠EVN and increased power prices for households and factories.
