SHANGHAI, June 6 (Reuters) – China’s top securities regulator on Saturday urged the country’s $13 trillion fund industry to support domestic innovation, but ‌warned against excessive speculation and concept hype.

Wu Qing, chairman of ‌the China Securities Regulatory Commission (CSRC), told a conference that fund managers must not make blind ​bets on certain sectors or launch funds when share prices are high to make a quick buck.

His call comes amid fierce Sino-U.S. competition in technology, and global investor fever toward artificial intelligence.

“China’s booming emerging and future industries urgently ‌needs capital support,” Wu said ⁠in a speech posted on the watchdog’s website.

China’s fund industry should focus on national strategies, and also “needs to improve ⁠global competitiveness and the ability to cope with external shocks.”

Wu’s speech came a day after the CSRC tightened oversight of the country’s $3.4 trillion private fund ​industry, and ​weeks after Beijing clamped down on “illegal” ​cross-border investment.

Meanwhile, volatility is increasing ‌in global markets. On Friday, U.S.-traded chipmakers plunged, wiping out about $1.3 trillion in market value.

“External uncertainties are rising, global financial markets are fluctuating at high levels and global assets are undergoing a major rebalancing,” Wu said.

“At the same time, a new wave of technological revolution led by artificial intelligence ‌urgently needs a more compatible financial system.”

Wu ​urged China’s private equity firms to play ​a more “strategic and fundamental” role ​in supporting innovation, and step up long-term investment in early-stage, ‌hard-technology start-ups.

Fund managers should also embrace new ​technologies such as ​AI to empower their business, Wu said. But he warned against concept hype, convoluted investment structures and excessive speculation.

Regulators will also tighten ​supervision of computer-driven program ‌trading to create a more level playing field and prevent unfair ​use of technologies, Wu said.
