South and North Korea will use the same flag at next month's Winter Olympics. The Olympics are from the 9th to the 25th of February. They are in the South Korean city of PyeongChang. People were worried about North Korea attending the games. Tensions between the two countries are high because North Korea has tested many missiles. However, after high-level talks, both countries decided to use a "unified Korea" flag at the games. They will also enter a joint ice hockey team. This might mean that relations between the two countries are improving.

The thaw in relations could open the door for more peace talks. The Koreas have been divided since the 1950-53 Korean War. There have been many attempts to improve ties between the two. The Winter Olympics could help this. The cross-border road will open for the first time in two years. However, not all Koreans are happy with this news. Thousands of people signed an online petition asking for South Korea's president to forget about the plan. South Korea's hockey coach is not happy. He said a united hockey team could damage South Korea's chances of winning a medal.
