European stocks fell on Wednesday as an escalation in the U.S.-China trade dispute brought a six-session winning streak to an end.

"It's more difficult to dismiss this on the basis that ... little has happened in real terms."
All European sectors were in negative territory, with those most exposed to action on tariffs taking the most points off the STOXX. Basic resources .SXPP fell 3.3 percent and autos .SXAP dropped 1.7 percent.
