McClay said the announcements had addressed tax differences that existed for goods imported via cross border e-commerce compared with similar items imported via normal trade channels.
"We are in the process of examining the implications of these announcements," McClay said yesterday.
"On first look they do not appear to be discriminatory against any particular country."
He said it was "any country's prerogative" to set its own tax policy.
The e-commerce changes come as Prime Minster John Key and McClay prepare to head to Beijing next week for talks including discussions around an upgrade to New Zealand's free trade agreement with China, which entered into force in 2008.
