LONDON, July 11 (Reuters) - European stocks fell on Wednesday as an escalation in the U.S.-China trade dispute looked set to bring a six-session winning streak to an end.
The pan-European STOXX 600 index was down 1.1 percent by 0905 GMT, while Germany's export-heavy DAX fell 1.2 percent.

Though investors have been looking positively towards the second-quarter earnings season, the increasingly uncompromising rhetoric on trade has weighed on equities recently.
"It's getting a bit more real for markets now," Ken Odeluga, market analyst at City Index, said, referring to the United States' threat of more tariffs.
"It's more difficult to dismiss this on the basis that ... little has happened in real terms," Odeluga added.
All European sectors were in negative territory, with those most exposed to action on tariffs taking the most points off the STOXX. Basic resources was down 3.1 percent and autos down 1.7 percent.
