According to the draft text for the 28-29 June EU Summit

  • EU leaders slam US metal tariffs
  • EU leaders to seek ways to improve functioning of WTO

Apart from that there's also the discussion on asylum policy as mentioned here earlier - an outlier to help Merkel and Germany.

But yeah, no surprises here that they are against the metal tariffs as they have been on this rhetoric for quite some time now. Still yet to hear of any concrete developments though.
