May 1 (Reuters) - Citigroup ( C/PN ) has hired former U.S.

Trade Representative Robert Lighthizer as a senior adviser on

global trade, the bank said in a statement.

"Given our global presence, having Ambassador

Lighthizer's insights into the dynamics facing global trade is

very valuable to us and our clients," a Citi spokesperson said.

The ambassador will not be a full time employee, the

spokesperson added. Lighthizer met recently with groups of Citi

clients and discussed U.S. president Donald Trump's

administration

tariff strategy

and potential

trade deals

.

The Wall Street Journal reported Lighthizer's hiring

earlier on Thursday.

During Trump's first term, Lighthizer played a crucial

role in the imposition of hefty tariffs on Chinese imports and

the renegotiation of the North American Free Trade Agreement, or

NAFTA, with Mexico and Canada.

Corporations are increasingly turning to advisers to seek

guidance on how to navigate the economic uncertainty triggered

by Trump's tariffs, which have disrupted long-established global

trade norms.
