May 17 (Reuters) - European stocks snapped a three-day winning streak on Friday amid global trade jitters after Beijing ratcheted up its war of words with Washington, while the end of Brexit talks between British political parties put a lid on risk sentiment.
The Chinese Communist Party's People's Daily used a front page commentary to say the trade war would never bring China down, while talks on Brexit between Britain's opposition Labour Party and the governing Conservatives ended without agreement.
The pan-European STOXX 600 index fell 0.4%, sliding from Thursday's 10-day closing peak. The benchmark posted a 1.2% weekly gain, however, its best performance since early April.
Ben Lofthouse, head of global equity income at Janus Henderson, said investors "have moved from being slightly risk-on to risk off".
"Markets don't deal well with circumstances that are not well rehearsed. For global equities, trade is on people's mind more than Brexit."
Germany's exporter-heavy DAX declined 0.6%, with BMW shedding 5.2% as its shares traded ex-dividend.
Milan-traded shares fell 0.2%, while peers in Paris and London edged 0.2% and 0.1% lower, respectively. The process of the United Kingdom's complex divorce from the European Union was jolted by the opposition Labour Party pronouncing the death of last-ditch talks due to deepening fractures in Prime Minister Theresa May's government.
The news knocked sterling but supported the shares of exporters on the FTSE 100, as a softer pound broadly boosts the value of their overseas earnings.
