HANOI, May 20 (Reuters) - Vietnam's finance ministry said on Tuesday that state-owned energy company PetroVietnam is looking to increase crude oil purchases from Exxon Mobil XOM.N, following a working visit with several Vietnamese firms to the United States.
The ministry said it held talks with U.S. Customs on boosting cooperation in combating transshipments through the Southeast Asian nation, as part of Vietnam's efforts to strengthen its trade ties with the United States.
