Thailand's Prime Minister Srettha Thavisin said on Sunday the country expected to receive an investment of at least $5 billion from Tesla (TSLA.O), Google (GOOGL.O) and Microsoft (MSFT.O).

"Tesla would be looking into an EV manufacturing facility, Microsoft and Google are looking at data centers," he said, without detailing whether the $5 billion was expected to be a combined investment or made individually by each company.

Tesla, Google, and Microsoft did not respond immediately to requests for comment.

Srettha spoke to reporters in Bangkok after attending the U.N. General Assembly in New York where he also talked with company executives earlier this week.

Fresh foreign investment would boost Thailand's flagging economy, which is expected to grow by 2.8% this year, less than previously projected, due to weaker exports.
