Dr. Park, Sung Jun (Associate Research Fellow) has found that transition in the conflict index, identified by GDELT, corresponds to the changes in international relations as understood by us to the certain extent, and captures more accurately the changes in conflict between two countries as compared with the tone information provided by the GDELT Event Database.
In this report, he constructed a conflict index based on the average tone information and the number of events provided by GDELT Event Database, and observed changes in relations between countries using such an index. It was confirmed that: Korea-Japan disputes were drastically intensified due to Japan’s restriction on the export of high-tech materials used in semiconductors and displays in July 2019; Korea-China relations deteriorated considerably after Korea announced its intention to deploy THAAD and China imposed an unofficial boycott in the first half of 2017; South Korea-North Korea relations significantly deteriorated due to PMD mine incident in 2015, nuclear test and launch of satellites in 2016; U.S.-North Korea relations were most hostile in 2016 when America citizens were arrested in North Korea UN Security Council resolution was adopted to impose additional sanctions on North Korea, and North Korea has carried out the test launch of the long range ballistic missiles; U.S.-China relations deteriorated sharply by the military activities in the contested South China Sea, the closure of the Chinese consulate in Houston, and the closure of the U.S. consulate in Chengdu in 2020; and Australia-China conflict fully began in 2020 when Australia stood on the side of the United Stated and called for an investigation of COVID-19.
“This study focused on the derivation and verification of conflict index. I expect that this index can be used to analyze and forecast international relations and the impact of conflicts between countries on the economy of such countries and worldwide,” explains Dr. Park.
