WASHINGTON, Nov 5 (Reuters) - Executives of MSC, Rolex,

Partners Group, Mercuria, Richemont and MKS

took part in a meeting of Swiss business leaders with U.S.

President Donald Trump in the Oval Office on Tuesday, according

to a statement seen by Reuters.

Switzerland is facing 39% U.S. tariffs on imports of its

goods and both its government and private sector have been

working to persuade Trump to reduce the levy.

The executives said the meeting was "highly constructive," but

that they did not engage in any negotiations with Trump, who

revealed on Tuesday that he had met senior representatives from

Switzerland to discuss trade, among other topics.

"We expressed our belief that a bilateral trade agreement

would further enhance economic collaboration in a manner

beneficial to Switzerland and the United States," the statement

said.

The letter was signed by Diego Aponte, president of shipping

group MSC, Marwan Shakarchi, CEO of gold refiner MKS PAMP Group,

Rolex CEO Jean-Frederic Dufour, Alfred Gantner, a founder of

private equity firm Partners Group, Daniel Jaeggi, president of

energy trader Mercuria, and Richemont Chairman Johann Rupert.

Last month, Swiss companies Mercuria and Partners Group pledged

more than $6 billion in U.S. energy investments as part of

efforts to lower the tariffs.

Mercuria's planned U.S. energy investments could include

measures to boost new power generation, carbon capture and

storage, as well as U.S. oil recovery, a source said at the

time.

An MKS spokesperson confirmed Shakarchi took part in the

meeting. Representatives from the other companies did not

immediately reply to requests for comment.
