South Korea will keep pushing for corporate tax reductions as promised, the nation's top economic policymaker said Monday, adding that the tax burden on companies here remains higher than in other major economies. Finance Minster Bahk Jae-wan made the remarks amid opposition from politicians over the government's stance on the country's tax policies. The Lee Myung-bak government has been seeking to reduce income and corporate tax rates since its inauguration but many lawmakers oppose the plan, saying that it will end up benefiting mostly wealthy people.
