The International Olympic Committee is pushing South Korean organizers to complete venues in time for crucial test events ahead of the 2018 Winter Games in Pyeongchang.

The IOC's coordination commission wrapped up a three-day visit - and its fifth overall trip - to Pyeongchang to check on preparations for the games.

Commission chair Gunilla Lindberg says ''the venues continue to progress rapidly'' and ''the competition sites remain on schedule for the games.''

However, she warned that ''some delivery dates are very close to the start of the test events.''

Test events in Alpine skiing, freestyle skiing and snowboarding are due to be held in early 2016.

Lindberg says ''it is important that Pyeongchang 2018 delivers these events successfully and, in particular, the test events next February, in order to create a solid basis'' for the games.
