Guo finished with 492.3 points and set an Olympic record for a final round score with 102.3 points in the deciding portion of the event. Russia's Natalia Paderina of Russia took the silver with 489.1 points and Nino Salukvadze of Georgia earned bronze with 487.4 points. The nations of the second and third-place finishers have made international headlines in recent days due to a military conflict that began in South Ossetia, a region that both Russia and Georgia have claimed as their own in recent years.
The United Nations and the European Union both officially recognize South Ossetia as part of the Republic of Georgia.
Russian bombing campaigns in Georgia this weekend have reportedly resulted in over 1,500 casualties.
"It's very difficult for us Georgians because of everything that's going on at home," said Salukvadze. "It was nice that Natalia Paderina came up to me after and gave me a handshake."
Salukvadze said she thought Saturday that the Georgian Olympic team might choose to withdraw from these games. However, a phone call from the Georgian president Saturday night urged the athletes to remain in Beijing.
"Last night, the president (Mikheil Saakashvili) called us and told us we had better stay in Beijing. We were up until one or two o'clock in the morning. All we could think about was Georgia," said Salukvadze.
