Last year, South Korean President Moon Jae-in declared that the Republic of Korea wanted to participate in the Chinese One Belt One Road (OBOR) Initiative in Chongqing. And this year, Liaoning province decided to join China’s OBOR link to the Korean Peninsula. Although South Korea is an important U.S. ally, why would it want to participate in the Chinese OBOR? There are four reasons.
First, connecting South Korea to the rest of Eurasia by the OBOR has symbolic meaning for South Koreans. Since the outbreak of the Korean War nearly seventy years ago, South Korea has been disconnected from the continent, effectively becoming an island since it could no longer access North Korean territory. Many South Koreans have sought to reconnect with the rest of Asia to escape from their isolation, where the country felt more similar to Japan and the United Kingdom than a country with a one-thousand-year-old culture and a shared history with their northern neighbors. South Korean constitutional law even includes North Korean territory under South Korea’s domain (Article 3). Thus, the present division between the two Koreas brings many contradictions to the forefront of South Korean society. If South Korea can connect with North Korea through China’s OBOR, then Seoul can overcome these contradictions and fulfill the Korean people’s long-held wish.
Second, President Moon expects that participation in the initiative will mitigate tensions between South Korea and North Korea by creating joint economic opportunities. If South Korea connects with China through North Korea, South Korea can use multimodal transportation (the ability to transport cargo by land, air and sea). This will increase the efficiency of South Korean trade and its partners will become more varied than before. But South Korea would need to rebuild North Korea’s train infrastructure because it is too decrepit to use. After rebuilding the train system, South Korea can resume business with North Korea at the Kaesong industrial complex and Kumgang mountain. These investments and a new, broader economic relationship could help mitigate tensions on the Korean Peninsula.
Third, South Korea seeks to pioneer a new emerging market and expand its economic area. Last year, President Moon declared that the OBOR initiative and Moon’s new policies toward Southeast Asia and North Asia have a close relationship. "I am confident a link between the Belt and Road Initiative and New North, New South policies will lead to peace and joint prosperity in the region,” he said. If South Korean trains connect with China’s railway system, South Korea can export its commodities to Central and Southeast Asia more easily. This is especially true since President Moon is expanding South Korea’s economic ties with ASEAN as much as the other countries who surround the Korean Peninsula like Japan, China and Russia.
In the past decade, ASEAN became the second largest market to South Korea after China. Given that 24.8 percent of South Korea’s exports go to China, Seoul needs to expand into other markets to reduce its economic dependence, and therefore its political vulnerability, vis-à-vis Beijing. Indeed, South Korea had been confronted with Chinese political and economic pressure when Seoul decided to deploy the United States’ THADD system in response to North Korean missile threats. After political pressure from China, South Korea wants to focus on developing new markets, so participation in the OBOR is attractive to Seoul.
Fourth, South Korea can get energy resources more easily, variously and cheaply than before. South Korea is the third largest importer of liquefied natural gas (LNG) after Japan and China. And South Korea will soon buy even more natural gas than before because President Moon is planning to replace South Korean nuclear and coal power plants with natural gas and renewable energy. But LNG is more expensive than pipeline natural gas (PNG)—South Korea currently has to buy natural gas in its liquefied state because it can’t access the pipelines across North Korean territory. If South Korea can import PNG from Central Asia via China or from Russia, it can remarkably reduce the cost to import natural gas. (80 percent of South Korean gas imports currently come from five countries, with a high dependence on the Middle East and Australia.) South Korea needs alternatives for energy imports so they cannot be blocked or hindered by another country’s resource nationalism, a financial crisis or security reason. Through the One Belt One Road initiative, South Korea can raise the funds to build the pipeline and connect with Central Asia and other countries too.
The above four reasons are why South Korea wants to participate in China’s OBOR initiative, but it should not do so lightly. There are three consequences that Seoul must consider before it participates in the OBOR.
First, the financial cost of participation is very high because the South Korean and North Korean train systems are so different. North Korea’s double-track ratio is just four percent, meaning the majority of North Korea’s rail system can only handle a single train moving in one direction at a time. Then there is the problem of energy. South Korea’s trains operate at 25,000 volts, but North Korea’s run at 3,000. To use North Korea’s train system, South Korea has to rebuild the North’s current rail infrastructure, which uses more electricity than North Korea generates. Another problem is that North Korea’s current electricity production is just 4 percent of South Korea’s. So Seoul would need to invest in both North Korea’s rail system and electricity generation. According to a report by the South Korea Financial Services Commission, the cost of developing North Korea’s train lines and resolving its power shortages is $87.7 billion dollars. Given the estimated cost of rebuilding North Korean infrastructure, South Korea must consider how it will pay the tremendous bill.
Second is a security risk that is related to trust and leverage. If South Korea participates in China’s OBOR, Seoul may be confronted with a troubling security situation. It is true that South Korea can curtail the cost of energy imports by using Russian or Central Asian pipeline infrastructure, but should South Korea put its trust and energy security in the hands of North Korea? As has happened before, North Korea can change its relationship with Seoul based on how it perceives its national interest. This creates a possibility that Pyongyang can put a lot of pressure on Seoul by stopping energy supplies to the South.
Seoul also can’t guarantee financial business stability for South Korean companies working with the North. Upon a change in South Korea’s government, North Korea can forfeit South Korean facilities or end its business with South Korean companies. For example, during the last South Korea administration, a business owner who participated in the Kaesong industrial complex didn’t get enough recompense from the government. With such a track record, how could South Korean companies have faith in Seoul’s encouragement to develop economic ties with North Korea?
Regarding China, the situation is similar. South Korea’s intention to participate in the OBOR initiative is to reduce its dependence on China as a destination for its exports, but if South Korea participates in the OBOR initiative, the dependency ratio is likely to increase further because China’s reason for including South Korea in this initiative is to develop its Northeast provinces. China will use South Korea to develop the region as a hub of Northeast area. It means that South Korea is giving China a powerful card that could threaten Seoul in the future.
Third, Moon’s foreign policy could fail when South Korea participates in the OBOR initiative. What President Moon expects from the initiative is for OBOR to be the connection between his New Southern and New Northern policies, thus expanding South Korea’s economic and diplomatic influence. But the top nine ASEAN countries with the highest trade volume with South Korea are not participating in the One Belt One Road project, or have suspended or canceled their projects. In truth, most ASEAN countries have a skeptical view of this initiative. In August, Malaysian prime minister Mahathir Mohamad canceled the Chinese-funded $20 billion East Coast Rail Link (ECRL) and pipeline project. Singapore has been wary about Chinese projects like potentially building a canal or railway to bridge the Kra Isthmus and does not have any OBOR-related projects on its territory. Pakistan and Thailand also reconsider OBOR initiative and canceled it. Vietnam says it supports the initiative but it doesn’t participate in the initiative substantively. The most relevant countries with South Korea in ASEAN are hesitant to participate in the initiative.
