SEOUL--A group of 280 North Koreans arrived in South Korea on Wednesday, one of the largest peacetime crossings of the inter-Korean border, to spur on athletes from the two Koreas at the Winter Olympics starting Friday.

The delegation, made up mostly of a 229-member cheer squad, reached a border checkpoint by bus at around 0030 GMT, Seoul's Unification Ministry said.

In addition to the cheering squad, there were 26 taekwondo performers, 21 journalists and four North Korean Olympics committee members, including Sports Minister Kim Il-guk, the Unification Ministry said.

After security controls the group left for the Olympics venue in the alpine resort town of Pyeongchang.

At a rest stop along the way, female members of the cheer squad, all donning black fur caps, red coats and ankle boots, waved and smiled at reporters who were trailing them.

"Hello, hello!" one said, giggling shyly before getting back on her bus.

When one reporter asked whether they were fully prepared, another member quipped: "You'll know once you see. It's no fun if I tell you everything now," according to the South's Yonhap news agency.

Their arrival comes a day after a North Korean ferry crossed the border carrying a 140-strong orchestra to perform during the Games.

Members of the orchestra were seen leaving the vessel for rehearsals at Gangneung Arts Center early on Wednesday, wearing the same outfits members of the cheer squad were seen in.

The orchestra is scheduled to perform at Gangneung, near Pyeongchang, on Thursday and in Seoul on Sunday.

Aside from the sports officials, the group will be housed at Inje Speedium Hotel & Resort, a four-star luxury hotel roughly two hours' drive from the Olympic venue in Pyeongchang.

Days before the group's arrival, workers at Inje Speedium had placed banners around the premises welcoming the North Koreans, reading "We are one" and "welcome."

Police have been deployed to enforce safety at the resort.

The taekwondo performance team is scheduled to hold four shows during their stay in South Korea. Two demonstrations will be held near Pyeongchang, while the team will travel to the capital Seoul for the remaining two.

OIL REQUEST

After the art troupe arrived on Tuesday in a ferry, which is also being used as accommodation, North Korea has asked South Korea to provide oil to refuel the vessel, the Unification Ministry said on Wednesday.

Oil is a sensitive item and has taken center stage in global efforts to curb Pyongyang's nuclear and missile programs, with Washington calling for a drastic cut in energy supplies to the isolated country.

North Korea has virtually no domestic oil production, and has traditionally imported its fuel demand from China and Russia.

In December, the U.N. Security Council unanimously imposed new sanctions on the North, seeking to ban nearly 90 percent of refined petroleum exports to the country by capping them at 500,000 barrels a year.

"There was a request for oil support during our discussions with the North after the ship arrived, and we're reviewing it now," ministry spokesman Baik Tae-hyun told a news briefing in Seoul.

Asked about concerns that South Korea was making exceptions to the sanctions, Japanese Chief Cabinet Secretary Yoshihide Suga said it was important not to let up pressure.

"We must not be fooled by North Korea's 'smile diplomacy," he told a news conference in Tokyo.
