Asia markets turned positive on Monday but traders remained wary ahead of a potential rate hike by the Federal Reserve this week.
South Korea's Kospi finished up 0.97 percent or 20.2 points at 2,117.59, as investors shrugged off the political risks after President Park Geun-hye was removed from office last Friday.
Park left the presidential Blue House on Sunday, two days after the Constitutional Court's decision to uphold her impeachment by the National Assembly over a corruption scandal, which also involves Samsung's de facto chief Jay Y. Lee.
"(The South Korean ruling) implies that the Korean society chose reform and justice over concerns on near-term economics and stability," said CW Chung, managing director at Nomura Securities, in a Monday note.
"From now on, the issue is whether such political changes can lead to improvements in commercial laws and renovation in old-fashioned practices and eventually the re-rating of the Korean stock market," Chung added.
