* Global stocks under pressure, while bonds gain

LONDON/TOKYO, May 22 (Reuters) - Global stocks were slightly lower on Wednesday as investors sought safety in bonds, the Japanese yen and Swiss franc in muted trade amid renewed worries over the U.S.-China spat after reports Washington has another Chinese tech firm in its sights.
Relief over Washington's temporary relaxation of curbs against China's Huawei Technologies evaporated after reports that the White House is considering further sanctions on Chinese video surveillance firm Hikvision. of another blacklisting reinforced worries that U.S. President Donald Trump is looking beyond sealing a trade deal with China to a potentially bigger battle aimed at curbing Beijing's technology ambitions.
"I think the debate is just starting about what the implications of all this could be if it escalates. It's my biggest concern," said Simon Webber, lead portfolio manager on the global & international equities team at Schroders (LON:SDR).
The limits which were imposed on Huawei last week and eased on Monday had sent shivers through global semiconductor stocks as investors worried about disruption to suppliers of the world's No. 2 smartphone maker.
"If we get retaliation, if we start deconstructing supply chains, if we get countries asking whether they can rely on products and services overseas, then we'll have much more uncertainty and a much more worrying environment," said Webber.
MSCI world equity index .MIWD00000PUS , which tracks shares in 47 countries, was down slightly at 0905 GMT, as investors shunned assets considered risky in times of economic and political strife.
The reports rattled European and Asian stocks, with the euro-zone STOXXE .STOXXE down 0.1%.
London's FTSE 100 blue chips FTSE bucked the trend, rising 0.4% as sterling fell amid renewed worries about the country's messy exit from the European Union.
The Chinese markets, which have endured a volatile few months, were on the backfoot. The Shanghai Composite Index .SSEC closed down 0.5%.
The threat dampened Australia's post-election optimism slightly, but stocks .AXJO still hovered near the 11-year highs scaled on Monday.
"Some in the markets will continue to cling on to hopes of the United States and China reaching an agreement at the upcoming G20 meeting," said Masahiro Ichikawa, senior strategist at Sumitomo Mitsui DS Asset Management.
"But the ongoing trade conflict looks to be a protracted one, and its potentially negative impact on various economies is becoming a running concern."
Leaders from G20 nations are scheduled to gather for a summit in Japan at the end of June.
Australia's stocks index is the only major global bourse to notch up gains since Trump ramped up his battle with Beijing on May 6, largely due to the election euphoria, while South Korea's KOSPI .KS11 is the biggest loser.
