Chase Manhattan

(CMB)

is trying to strike an agreement to buy the U.K.'s

Robert Fleming Holdings

for about $6 billion, according to

Bloomberg

.

The news service, citing people familiar with the situation, said Saturday that Chase could wrap up its bid to acquire the big merchant bank as early as next week.

Officials at Chase couldn't immediately be reached by

TSC

to comment.

The deal would help Chase expand in Asia, where Fleming manages more than $30 billion for individual and institutional investors and controls

, once Hong Kong's biggest broker, Bloomberg said. New York-based Chase opened offices in Asia 75 years ago and employs 3,500 people in 12 Asian countries, Bloomberg reported.

Fleming has 7,800 employees and manages more than $140 billion, including a $35 billion joint venture in the U.S. with Baltimore-based
