In today's Focus on Politics podcast, Political Editor Jane Patterson interrogates the ramifications for New Zealand of Russia's war against Ukraine.

"The countries which are close neighbours with a shared history and culture appear to be a ruthless enemy, and the nations which are so far away with different historical backgrounds appear to be a real friend," - Ukraine Ambassador designate Kateryna Zelenko

Whether the global ripples from Russia's invasion of Ukraine crash onto New Zealand's shores may depend largely on the actions of China - and what is done in response.

New Zealand has followed other countries in imposing sanctions against Russian individuals, institutions, and assets, and states linked to it could soon follow.

China is close to Russia both geographically and diplomatically. Its position on the war is not yet clear, but as New Zealand's largest trading partner any sanctions against it could mean serious economic repercussions.

Experts doubt China will take sides, but multilateralism and being heard on the global stage are important to New Zealand - and if China does step in, choices will have to be made.

New Zealand's actions against Russia include a travel ban for hundreds of individuals, sanctions on President Vladimir Putin and his security council of 12, one bank, and 18 other entities.

It means assets cannot be moved here, and prevents New Zealand's financial system being used to circumvent the sanctions of other countries, but the move marks a significant departure from the tradition of applying UN sanctions only.

The legislation, passed under urgency last week, marks a significant departure from a tradition of only applying sanctions in line with the UN.

The list of sanctions was published on Friday, with Foreign Minister Nanaia Mahuta promising more to come.

The National Party supported the legislation, with MP Gerry Brownlee saying it was a difficult situation for the entire world. Indeed, the threat is nuclear - with Putin saying Russia's weapons were on "special alert".
