TOKYO, Sept 13 (Reuters) - Japan's Mitsubishi UFJ Financial Group Inc (MUFG) has picked Amsterdam as its European Union investment banking base, sources with direct knowledge of the matter said on Wednesday, as global financial institutions prepare for Britain's exit from the EU in 2019.
MUFG has also decided to open a branch in Paris for its investment banking unit, said the sources, who were not authorized to discuss the matter publicly.
An MUFG spokeswoman declined to comment.
