BEIJING - The United States remained the top destination for China's overseas portfolio investment at the end of the second quarter, State Administration of Foreign Exchange data showed Wednesday.

China made about $312 billion of portfolio investment, including investment in equities and bonds, in overseas markets by June, with $116.6 billion invested in the United States, the administration said on its website.

China's Hong Kong was second, attracting $72.4 billion, followed by the Cayman Islands with $20.3 billion.

Total overseas portfolio investment was 11.11 percent higher compared with last year.

In a breakdown, China made $186.7 billion of overseas equity investment and $125.4 billion of overseas bond investment, the administration said.

China started to publish country-specific figures on overseas portfolio investment in January this year after the country formally joined the Coordinated Portfolio Investment Survey conducted by the International Monetary Fund, at the end of 2015.
