By Jack Kim SEOUL (Reuters) -North Korea has no interest in any policy or proposals for reconciliation from South Korea, the powerful sister of its leader Kim Jong Un said on Monday, in the first response to peace overtures by the South's liberal President Lee Jae Myung.

For the first time since South Korea’s new president assumed office, Pyongyang explicitly nixed the Lee administration’s pro-dialogue approach to North Korea.

The first flight to North Korea operated by Russian carrier Nordwind took off from Moscow's Sheremetyevo airport carrying over 400 passengers.

In another pointed statement issued on July 29, Kim Yo-jong, the influential sister of North Korean leader Kim Jong-un and a senior official in the ruling Workers’ Party, dismissed renewed American interest in resuming dialogue as misguided nostalgia.

Russia will launch direct passenger flights from Moscow to North Korea 's capital Pyongyang on Sunday, Russian authorities said, as the two former communist bloc allies move to improve ties following Russia's invasion of Ukraine in 2022.

North Korean leader Kim Jong Un said the country would achieve victory in "anti-imperalist, anti-U.S." battles, as the country marked the anniversary of the Korean War armistice, state media reported on Sunday.

Since his election, South Korean President Lee Jae Myung has tried reverse the hardline stance of his predecessor toward Pyongyang.
