South Korea's National Assembly has kicked off an interpellation session -- where lawmakers have the chance to grill the country's top government officials.<br />Over four days,.. cabinet members will be questioned on a range of topics,... from politics and foreign affairs to the economy.<br />For more, our political correspondent Kim Min-ji joins us on the phone.<br />Min-ji, what were some of the issues brought up today?<br /><br /> Ji-yoon. We're just about two hours into the session now,... and the topics brought up so far include the government's income-led growth policies.<br /> The ruling party said that the government will have to do more to explain the impact of these policies,... especially as people are going through hard times during the transition.<br /> It also defended the policies, saying they will change the country's economic paradigm -- and claiming that the current economic hardships are a result of the previous conservative government's policies, including its interest rate cuts,... and real estate policies.<br /> However, the opposition bloc said that the policies of the current government have failed and it's doing more harm than good.<br />It called for an all-out change in policy direction -- and criticized the government for using taxpayers money excessively to implement its costly policies.<br /> On North Korea, the biggest issue of course has been the parliamentary ratification of the summit declaration reached in April.<br />The opposition lashed out at the fact that it comes with such a hefty price tag,... saying people's understanding has to come before ratification as it's also a burden on them.<br /> It added that ratification of the summit can also only take place after North Korea shows sincere commitment to denuclearization.<br />The session will continue in the afternoon so I will have more updates in our later newscast.<br />This has been Kim Min-ji from the National Assembly. <br />
