AMP Capital has raised $450m (€330m) and closed its Infrastructure Debt Fund II (IDF II), with China Life among those investing the fund.

The raising takes the total amount committed to the fund to more than $750m.

IDF II had its first close in August last year, with an initial 17 investors contributing more than $300m.

The fund has now attracted 40 institutional investors from Japan, South Korea, Switzerland, the UK and the US.

AMP Capital has since made investments for the fund, including subordinated debt financing for New York power generation facility Astoria Project Partners.

Andrew Jones, AMP Capital global head of infrastructure debt, said it was on track to meet its final target of $1bn.

“This reflects increased interest in infrastructure debt globally,” he said.

AMP Capital’s first debt fund, IDF I, was closed to new investment in 2012 after raising $500m globally.
