The pan-European Stoxx 600 closed provisionally down by 0.6 percent, with all major bourses in negative territory.
Europe's basic resources recovered from losses earlier in the day, rallying over 1 percent in the afternoon. They had previously been weighed down amid heightened concerns of a global trade war. President Donald Trump is widely expected to unveil up to $60 billion in import duties on Chinese goods by the end of the trading week. Investors are anxious the looming charges could escalate into a full-blown trade war, threatening global economic growth.
Oil and gas also performed well, up 0.7 percent, with Spanish wind turbine manufacturer Siemens Gamesa topping the sector.
