Philippine President Rodrigo Duterte's visit to Japan yielded investment commitments worth $1.85 billion from private companies, a member of his administration said Thursday.

Trade and Industry Secretary Ramon Lopez said the investments, forged through memorandums of understanding and letters of intent, are in the automotive, egg-laying technology, optical imagery, and biofuel fields, among others.

"The fresh commitments may generate between 200,000 to 250,000 direct and indirect jobs over the coming years," Trade Undersecretary Nora Terrado said in a separate interview.
