(New throughout, adds detail about deals, Vietnamese prime minister's visit, GE share price)

SEATTLE, May 31 (Reuters) - General Electric Co said on Wednesday it had signed deals in Vietnam worth about $5.58 billion for power generation, aircraft engines and services, its largest single combined sale with the country in GE's history.

The agreements came as Vietnamese Prime Minister Nguyen Xuan Phuc was on a three-day trip to the United States that was to include meeting with President Donald Trump and signing deals with U.S. companies for high-tech goods and services worth $15 billion to $17 billion.

GE's agreement with Vietjet Aviation JSC includes 20 jet engines made by CFM International, a joint venture of GE and Safran SA of France. It also includes a 12-year engine service contract for 215 LEAP-1B engines on 100 Boeing 737 MAX aircraft that Vietjet has ordered, GE said.

GE's power unit signed a memorandum of understanding to build two 750-megawatt gas fired turbine power plants in conjunction with state energy group PetroVietnam, using the Blue Whale Gas Field. PetroVietnam signed an agreement with the Vietnamese unit of Exxon Mobil Corp in January to develop the field, Vietnam's largest gas project.

GE also signed a joint development agreement to erect an 800-megawatt wind power facility. Partners in the agreement are Phu Cuong Group and International Mainstream Renewable Power, GE said.

GE's shares were flat at $27.35 in afternoon trading on the New York Stock Exchange. (Reporting by Alwyn Scott; Editing by David Gregorio)
