The European Commission’s proposing a new law to stop foreign companies using government aid to undercut European ones. There are strict rules about what financial help European businesses can accept from their governments — but at the moment those don’t extend to foreign companies. Politico EU reports that it is part of the bloc’s new defensive push on the trade front, as Brussels flexes its muscles to protect home-grown companies against the economic might of foreign powers, including an ascending and more assertive China. The EU regulation will give the Commission the power to investigate large mergers with foreign companies and public procurement bids of businesses receiving foreign state aid. Beyond this, the Commission will be able to independently patrol for unfair subsidies in the single market.
