South Korea's finance minister said on Wednesday the government would deploy all possible measures to stabilize financial markets if needed after President Yoon Suk Yeol declared martial law in an emergency national address. "We will mobilize all possible financial and foreign exchange market stabilization measures, including unlimited liquidity injections," Choi Sang-mok said in an emergency meeting with top economic officials in Seoul. South Korea's parliament, with 190 of its 300 members present, passed a motion on Wednesday requiring the martial law declared by President Yoon Suk Yeol to be lifted, live TV showed.
