Bach said at a press conference in Lima that the International Olympic Committee was in contact with different governments about the situation, but said there was "not even a hint" that the Games were under threat.
Bach added that the United Nations are now finalising an "Olympic Truce" resolution due for approval at a General Assembly in November.
The Pyeongchang Games, the first Winter Olympics in Asia to be staged outside Japan, will run from February 9-25.
"We hope that these discussions, to which we contribute, will be successful so this can be approved at the UN General Assembly in November".
"We are also keeping the door open for athletes of the DPRK", he said.
Bach said meanwhile that he was unaware of any nervousness on the part of other nations about sending there athletes to South Korea.

When asked if some national teams may pull out due to safety fears, Bach told Inside the Games: "I don't see this [as a concern] right now because there is a clear commitment". "We hope we're appealing that diplomacy and peace will prevail on the Korean peninsula".
Lee Hee-Beom, the president of the 2018 Winter Games organising committee, later said he was confident of delivering "perfect security" for the Games, admitting no contingency plans had been drawn up.
The executive board is meeting Monday and Tuesday ahead of the four-day IOC Session in Lima which will also get updates from upcoming hosts Pyeongchang (Winter 2018), Tokyo (Summer 2020) and Beijing (Winter 2022).
"There's no plan B as the Olympics are based on an Olympic Truce", he said.
"We will have a flawless security and safety Olympic Games".
After taking office in May, South Korean President Moon Jae-in vowed to use the Olympics to try to ease animosities with the North.
