MILAN/LONDON: European shares steadied on Wednesday as trade war fears which had pushed indexes into the red during the previous session eased on the prospect of a meeting between the U.S. and Chinese presidents at a G20 meeting.

The pan-European STOXX 600 benchmark index rose as much as 0.5 percent before ending flat on the day at 357 points, while the Euro STOXX 50 index added 0.1 percent.

German tyre maker Continental declined more than 4 percent with traders mentioning a "cautious tone" from the company during a conference.

Worries over Washington's protectionist policies and slowing growth are expected to keep investors on the edge throughout 2019, a Reuters poll showed, with the STOXX seen hitting 373 points, up just 2.2 percent on the year.

Telecoms hit their highest level since mid-May on hopes of sector consolidation sparked by the European Commission's unconditional clearance of the acquisition of Tele2's Dutch unit by Deutsche Telekom.

The sector pared some gains to end up 0.1 percent.
