Russia’s invasion of Ukraine makes the cooperation agenda for pandemic recovery much harder. It has also threatened to derail the G20 summit altogether. Nevertheless, the global community has shown its ability to rapidly coordinate economic sanctions and present a largely united front against a war of aggression. Despite the tragedy from the conflict and its effect on the global economy, this also underlines the security dimension of economic interdependence. The coordinated economic and financial sanctions on Russia appear to be imposing huge costs on the Russian economy. Whether they help in ending the conflict depends on other factors but the sanctions have made Russia internalise some of the costs of its aggression. Economic sanctions and trade measures can help to constrain bad behaviour and give the global community non-military tools to fight back in the extreme against military aggression. The collective action, however, can only be effective given high degrees of economic interdependence, where countries need each other in sustaining their economic activities. China is more integrated into the global economy and appears to be distancing itself from Russia. Maintaining the interdependent open economic system is a powerful weapon for securing peace. Crucial to that is an effective multilateral trading system with a stronger World Trade Organization (WTO) at its centre. The crisis in Ukraine can be a catalyst for strengthening the scaffolding that holds the global economy up. Core of trade The WTO, at the heart of the global trading system, is in crisis. For two decades it has largely failed to update global trading rules or open new markets. Bilateral free-trade agreements have chipped away at those objectives although more recently the Regional Comprehensive Economic Partnership (RCEP) and the Trans-Pacific Partnership agreement have made progress for its members. Since the end of 2019 the dispute settlement body at the WTO has had no judges thanks to a veto by the United States , so it can no longer enforce the rules to keep markets open. The multilateral trading system can be revived by setting about the reform of the WTO. Maintaining the interdependent open economic system is also a necessary condition for economic recovery from the coronavirus pandemic . Any recovery will be short lived without open international markets that are essential to a prosperous Asian and world economy. The G20 is the only group that can mobilise support from the world’s most powerful economies to reform global institutions such as the WTO. A stronger trade regime with the WTO at its centre is necessary to support the recovery and face new economic challenges in the post-pandemic era. Ukraine envoy to Indonesia urges G20 to put Russian invasion on agenda Indonesia must find a way to keep the G20 focused on cooperative outcomes and directed towards economic recovery. The challenge is to focus on a small number of strategic outcomes instead of a long and unachievable wish list. Clear progress on WTO reform will be a monumental legacy of Indonesia’s leadership of the G20. Indonesia has a moral authority that few other countries do to set a clear strategic direction for reforming the WTO. Indonesia stepped forward to articulate a comprehensive plan for WTO Reform at the Osaka G20 Summit in 2019. This initiative was welcomed and attracted support from other G20 countries, leading to the Riyadh Initiative to the Future of the WTO in 2020, but progress has been slow. Support for reform Indonesia should now propose a G20 Common Framework for WTO Reform strategy paper to guide the reform initiative. Indonesia’s position as chair of the Group of 33 developing countries in the WTO can build bridges on this issue between the main protagonists in a geopolitically fraught environment. Indonesia successfully led the conclusion of the RCEP, the world’s largest regional trade agreement, at a time of rising protectionism, great power strategic competition and the pandemic-induced recession. The days of big multilateral deals like the Uruguay Round are likely over, with agreement by all members on everything necessary to conclude one, having seen the death of the Doha Round. In a world of bottom-up rule-making and concerted unilateral action, what is needed is leadership and action led by multilateral principles. The world trading system is at risk of fragmenting as new rules are forged around political blocs. Multilateral rules are needed in new areas such as the digital economy, and regional action can be directed towards that goal. Ukraine should be off topic at G20 summit A strategy is needed to revive the WTO’s three main functions of trade liberalisation, the monitoring of trade policy, and resolving trade disputes. There are sensitive issues such as developing country status and subsidies, but there are also less contentious areas for quick progress such as transparency and the notification of new trade measures. A signal by the G20 on the willingness to set the direction and scope of WTO reform would help to move things forward. The extensive work that has been completed on WTO reform can inform the G20 Common Framework and the stages of its implementation. The G20 is not a negotiating forum but can mobilise the political will necessary for progress in the WTO and elsewhere. As one of the supporters for WTO Reform, Indonesia should join the Multiparty Interim Appeal Arbitration Arrangement (MPIA) that replicates the function of the WTO’s Dispute Settlement Body’s function, alongside the European Union, China , Singapore, Australia and 20 other WTO members. Finding a solution to have a functioning WTO dispute settlement system is a top priority but until then, as a concrete, confidence-enhancing step, Indonesia can announce its preparedness to join MPIA in the lead-up to the G20 Summit and call on others, especially in the region, to follow. That would reinforce Indonesia’s trade policy leadership credentials at the same time as supporting WTO reform. Indonesia has the opportunity and responsibility to put the global economy on the right track. It can bring India – the perennial trade policy spoiler – and Brazil into an action plan for their G20 presidencies and help to bring India closer to East Asia’s supply chains. Indonesia chairs Asean (the Association of Southeast Asian Nations) in 2023 and can carry forward the momentum with regional implementation of G20 outcomes as RCEP gears up this year. A stronger multilateral trading system with an effective trade organisation will be a necessary condition to recover stronger, including to discourage the escalation of the already increasing geopolitical tensions. The G20 presents an important opportunity for Indonesian President Joko Widodo to focus on the strategic priorities where Indonesia has traction and can lead by example.
