President Park Geun-hye will focus on preparations for the upcoming U.N. sessions she will attend later this month, where she plans to call for global attention to North Korea's nuclear and missile issues, a source at Cheong Wa Dae said Sunday.

Park is scheduled to visit New York from Friday to Monday to attend the U.N. General Assembly and the U.N. summit for sustainable development.

Without any appointments scheduled outside the presidential office, she plans to only focus on preparing for speeches and other activities at the U.N. meetings until she departs for New York on Friday, according to the source.

"Park will place her attention this week on her planned trip as North Korea has raised its nuclear and missile threats and many high-profile world leaders will join the U.N. sessions to mark the 70th anniversary of the establishment of the world body," the source said.

North Korea has hinted at launching what it called "a series of satellites" ahead of the 70th anniversary of the founding of the ruling Workers' Party on 0ct. 10. It has also threatened to conduct a fourth nuclear test.

During her planned keynote speech at the U.N. General Assembly, Park plans to call for an end to the North's nuke and missile programs, but the specifics and tone of the speech are likely to be adjusted, depending on the situation on the Korean Peninsula, the source added.

She urged the North to abandon its nuclear weapons program and make a strategic choice for economic development during her speech at the U.N. session last year.

Park is also expected to arouse global attention to prevalent sexual violence during conflict in a bid to prod Japan into a sincere apology for Tokyo's wartime sex slavery. North Korea's human rights record is likely to be dealt with during her speech as well.

Park is also set to address the U.N. summit on Sept. 26, which is designed to adopt the post-2015 development agenda, according to the presidential office.

The new development goals will serve as a guideline for sustainable development over the next 15 years as a follow-up to the Millennium Development Goals aimed at eradicating extreme poverty. (Yonhap)
