According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic steel exports to 2.44 million tons, down 2.4 percent year on year, after January down 3 percent, the second consecutive month of decline. In the past three years, South Korea's steel exports have decreased year by year, from 31.67 million tons in 2017 to 30.44 million tons in 2018 and 30.38 million tons in 2019. Instead, South Korea's steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.
