As part of Prime Minister Shinzo Abe’s state visit to China – the first by a Japanese leader in 11 years – he and Chinese President Xi Jinping are expected to announce 30 joint infrastructure projects.

Of course, there will probably be a raft of other announcements aimed at normalising the political relationship between the two Asian giants that share one of the largest economic relationships in the world, too.

But the most consequential of those may well be the infrastructure deals. That’s because, in welcoming Japan to undertake joint projects, China is signalling a change in approach to its “Belt and Road Initiative”.

Xi’s signature project has hit resistance both at home and abroad, and some of these fears have proved true, with failed projects bringing with them economic and political costs. So, for Japan, engaging with China in this way is pragmatic.

As Chinese policymakers search for ways to better deploy the country’s vast sums of capital abroad, they can draw on Japan’s experience in funding foreign ventures, which dates back to the 1970s. Japan too, suffered a geopolitical pushback.

And by understanding that the belt and road plan is here to stay and choosing to engage with it, Japan can help shape the initiative’s massive investments and get more business for its companies.

Japan is also making a broader hedge against an increasingly uncertain US relationship.

Asia needs a large volume of infrastructure investment to achieve growth rates that will continue to exceed the global average.

Competition between various sources of infrastructure investment is a positive development, as is some cooperation. Increased competition will result in improved outcomes, in terms of the scale and the quality of infrastructure investment, so long as recipient countries have the capacity to assess alternative project proposals, have good governance and are clear about the consequences of projects that fail.

Infrastructure investment that is undertaken adhering to principles of open tenders and transparency will reduce the likelihood of failed projects and improve the outcomes for both investors and host communities. But projects will still involve risk and inevitably not all will produce benefits for the investors and the recipient communities.

East Asia has a particular interest in leading cooperation to build up understanding of the principles needed to govern productive infrastructure investment and to help build capacity to manage infrastructure investment in recipient countries.

East Asia is home to established forums for cooperation with the Association of Southeast Asian Nations (Asean), the Asia-Pacific Economic Cooperation forum (Apec) and the East Asia Summit (EAS), and is home to major investors and recipient countries.

This cooperation needs a trans-Asian element that includes South Asian countries. South Asia is best and most constructively engaged through the EAS or in active economic arrangements such as the Regional Comprehensive Economic Partnership agreement. Getting it right in East Asia will help to get it right in the rest of the world.

Failed infrastructure projects – those that are not economically or socially efficient – create large losses for investors and do not bring needed benefits to recipient countries. They can also hamper investment elsewhere by causing investors reputational damage and reducing the capital available for investment.

Regional cooperation can help with building consensus around principles for investors and recipients, capacity to assess projects, capacity to put together tenders and with mediation between parties in the event of failed projects.

A region that has avoided legally binding cooperation due to diversity and complicated relationships will not readily or sensibly move towards a dispute settlement mechanism, even if it is a truly multilateral process. Cross-border infrastructure is already a contentious issue.

In infrastructure investment there will always be significant risk for both investors and recipients. Measures to diversify project and political risk by forming consortiums just as China and Japan have announced are a pathway to be encouraged.

The experience of some failed projects leading to large losses and recipient countries becoming indebted has caused concern and reputational damage in the global community. An investor often has little option but to swap debt for an equity stake to minimise further recipient losses. but that can be a poisoned chalice.

A third-party regional or multilateral process that mediates disputes after failed projects would help to avoid outcomes that cause suspicion and reputational damage and can limit economic costs. Such a process would need to be closely tied to the agreed principles for infrastructure investment and inform the proposals and implementation of projects. These processes might be mediated by established regional institutions such as the Asian Development Bank and the Asian Infrastructure Investment Bank and sensibly relate to existing multilateral institutions and processes such as the World Bank’s Multilateral Investment Guarantee Agency.

An independent external process that provides viable options for restructuring debt or resolving ownership of loss-making or non-performing assets can help to avoid contentious outcomes that spill over into geopolitical dealings.

Joint projects by China and Japan have opened up a conversation on principles for difficult cross-border infrastructure projects. Now China’s neighbours need to engage with China in a conversation about how to best to mitigate the risks and find ways to adequately resolve the failures, of which there will inevitably be some.
