European shares logged their worst on mounting worries that rising US-China tensions could take a toll on trade negotiations between the two countries. Sectors sensitive to tariff-related headlines including autos and mining stocks were down more than 0.4 per cent. Expectations that the world’s top two economies would strike a trade deal have been instrumental in driving the Stoxx 600 to a four-year peak. The benchmark index is now about 3 per cent away from its record high. Sectors considered as safe havens during times of economic strife, including telecoms and utilities, ended flat to marginally lower.
