It comes just days after the former leader of the Grand Duchy departs the EU executive’s helm.
Vice-President Margrethe Vestager and tax commissioner Paolo Gentiloni will on Monday meet IMF researchers.
The researchers investigated the impact of tax havens on global tax revenues. Luxembourg is a country of 600,000 people. It hosts as much foreign direct investment as the US.
The FDI in the Grand Duchy is worth $4 trillion, a 10th of the global figure. Gentiloni has said he wants to step up the EU fight against tax avoidance.
