LONDON, May 20 (Reuters) - Stock markets weakened on Monday as concerns mounted about an escalating fallout from a U.S. crackdown on China's Huawei Technologies.
Investors already on edge about an escalating U.S.-China trade dispute were further rattled after Beijing accused Washington of harbouring "extravagant expectations" for a trade deal, underlining the gulf between the two sides. shares had managed to reverse some of last week's losses on Monday after Washington said it would lift tariffs in North America, and as investors cheered apparent wins by Conservative incumbent parties in elections in Australia and India.
But the mood did not carry over to Europe, where weak corporate earnings added to the gloom.
The pan-European Euro STOXX 600 .STOXX extended earlier losses and was down 1.06% by 1100 GMT - the index, down 3.5% in May, is on track for its first monthly loss in 2019.
The German DAX .GDAXI slid 1.38%, while France's CAC 40 .FCHI weakened 1.39%.
U.S. President Donald Trump's government added Huawei to a trade blacklist last week, imposing restrictions that will make it difficult to do business with U.S. companies. repercussions quickly became evident as Google GOOGL.O suspended some business with Huawei. Europe, chipmakers Infineon Technologies IFXGn.DE , AMS AMS.S and STMicroelectronics STM.PA dropped sharply, falling between 6% and 12% on growing fears of a disruption to the industry's global supply chain. volatility continues to stem from announcements and interpretations of what is going on in trade disputes between the U.S. and its trading partners, but principally China," said Jasper Lawler, head of research at London Capital Group.
"China are unlikely to take Google's suspension of business with Huawei lying down."
On the positive side, a U.S. decision on Friday to remove tariffs on Canadian steel and aluminium prompted Canada's foreign minister to vow the quick ratification of a new North American trade agreement.
The MSCI index of world shares .MIWD00000PUS , which tracks shares in 47 countries, slipped 0.14%, leaving it 3.9% below its 2019 highs. The sudden return of trade war jitters has sent the stock market's year-to-date rally into reverse.
U.S. S&P 500 e-mini futures ESc1 dropped 0.51%.
Prominent investor Jim Rogers, who co-founded the Quantum Fund with George Soros, told the Reuters Global Markets Forum that he believed Washington and Beijing would soon announce a trade deal, although the current spat would not be the last time Trump tried to exploit the prospect of a trade war.
"These are negotiating tactics from Mr. Trump at the moment. What will happen is we will have some good news, the market will have a rally. It will probably be the last rally," he said.
