A deadline is looming for investment giant BlackRock to respond to a please explain from a US congressional committee.
The select committee is investigating whether the firm that manages an estimated $10 trillion of assets has been putting American's savings into Chinese companies blacklisted by the US government for human rights and security reasons.
The New Zealand government recently announced it's worked with BlackRock rock to create a $2 billion investment fund for renewable energy.
CNN correspondent Nicole Goodkind has been following the U-S investigation and says the committee's focusing on BlackRocks major investments in China.
