On the face of it, the RCEP is a positive step for cross-border investments. It further integrates trade between the two nations, along with Japan, South Korea, Australia and the 10 countries in the Association of Southeast Asian Nations (Asean).
But perhaps we should stop to ask whether the haste with which this is happening will generate equitable and sustainable benefits.
One of the main criticisms of globalisation is that, in an aggressive and politically driven push for economic integration, the institutional (legal, political) differences between trading and investment partner countries have been overlooked.
The US-China trade war in the past three years, and now Covid-19, have highlighted the differences in responses to trade, investment and the pandemic by countries with very different political and economic ideologies.
In particular, China is using its global power to expand its influence and reset the rules of trade relationships. New Zealand must be cautious about its exposure to Chinese influence at this level.
Rebalancing the books
Our analysis of foreign direct investment (FDI) application data from the New Zealand Overseas Investment Office from the beginning of 2017 to the end of 2019 shows two conflicting trends.
In financial and insurance services, and the information, communications and technology sectors, application approvals favoured the US and Australia. But in manufacturing, even after the US–China trade war broke out, approvals favoured China.
This greater receptiveness to Chinese investments in manufacturing might reflect the push for more economic integration with China in recent years.
But this approach needs to be scrutinised in light of the current stand-off between China and Australia.
The downside of economic integration
The recent call by Australia (supported by New Zealand, the EU and Canada) for an independent investigation into the origin of Covid-19 shows how much deeper institutional differences matter.
China imposed tariffs and other trade restrictions on Australian beef, barley, minerals, wine and most recently coal in response to that call and to Australian government criticism of Beijing's suppression of political dissent in Hong Kong.
In an ideal world, the free trade agreement between Australia and China and the much-hyped regional economic integration represented by the RCEP might have salvaged the relationship and allowed the parties to talk more openly about their disputes.
But the opposite has happened. The stronger economic relationship and mutual economic dependency have actually made China's retaliation even more painful for Australia. The less powerful party is always hurt more when a relationship goes wrong.
The lessons for New Zealand
New Zealand and Australia are not alone in being at something of a crossroads with China. Many countries are confronting the difficulty (impossibility, even) of balancing the pressure to be part of China's economic orbit and their fundamental institutional differences.
In essence, it is the tension between greater political and economic freedoms, and state intervention and control. The implications for resolving trade disputes and other economic disagreements are profound.
For that reason, New Zealand's FDI policies and application approvals should reflect a preference for countries with similar institutional conventions. While balancing its trade interests is critical for New Zealand, it should not be driven purely by immediate economic benefits.
New Zealand's FDI policies should reflect its own best long-term interests: continued regional economic integration with Australia, enhanced post-Brexit leverage of the political, historical and cultural links with the UK, and closer economic ties with developing economies (especially Commonwealth countries such as India and Malaysia).
In doing so, New Zealand will reduce the political and economic risks of over-integration with China and avoid the kind of conflicts based on deep institutional differences we are now witnessing.
