Japanese Foreign Minister Takeaki Matsumoto told lawmakers on Friday that Tokyo "cannot accept" Korea's plans to build a research station on Dokdo. Matsumoto said the Japanese government lodged a protest with the Korean government after confirming that Hyundai Engineering and Construction had been chosen to build the research station.
The Korean plan comes in response to the approval of Japanese textbooks that stress Japan's territorial claim to the Korean islets.
Meanwhile, Liberal Democratic Party lawmaker Shigeru Ishiba visited the Korean Embassy in Tokyo on Thursday and warned Ambassador Kwon Chul-hyun that Seoul-Tokyo relations could worsen due to the construction of the research station at a time when the Japanese people are having a difficult time overcoming the damage of the recent earthquake.
Kwon replied that Koreans who rolled up their sleeves to help Japanese earthquake victims feel betrayed by Tokyo's decision to authorize the textbooks.
