Hong Kong stocks closed down 1.61 percent Wednesday as a downgrade of China's growth outlook by the International Monetary Fund raised concerns about recovery in the world's second largest economy.
The benchmark Hang Seng Index fell 369.32 points to 22,554.93 on turnover of HK$63.80 billion ($8.22 billion).
The International Monetary Fund cut its 2013 growth forecast for China to "around 7.75 percent", a top official said, citing a sluggish global recovery which hurt exports.
It had previously predicted 8.0 percent growth in China.
"China-related stocks will likely remain under pressure as the economic slowdown is cooling investor interest in mainland-related shares," Capital Securities research director Jasper Tsang told Dow Jones Newswires.

"Investors withdrew their funds from the financial sector and turned to shares of smaller companies, so trading remained tepid today," Haitong Securities analyst Zhang Qi told AFP.
