NEW YORK/LONDON, July 22 (Reuters) - World equity markets were little changed and gold rose on Wednesday after the U.S. ordered China to close its consulate in Houston, fanning fears of worsening bilateral relations, while the euro gained further on the European Union's massive recovery fund.
Trading was choppy as many bourses around the world had been consolidating recent gains in equities. But the order for Beijing to shut its Houston consulate in three days spurred risk-off sentiment and a move to assets offering relative safety, such as gold and silver.

The surge in precious metals came amid China's growing demand for physical assets as gold is seen as a hedge against inflation and fears of currency debasement, and on the massive pumping of government and central bank stimulus into the economy.
The question is whether the Federal Reserve has limited or even eliminated investors' needs to address market risk, said Yousef Abbasi, global market strategist at StoneX Group Inc.
"We face several different challenges and the tail risks are getting higher and higher," Abbasi said, pointing to U.S.-Sino relations, the potential economic fallout from the coronavirus and uncertainty over the U.S. presidential election.
"Yet the market continues to climb higher. And it's telling investors these risks don't need to be addressed," he said.
