LAUSANNE, Switzerland (AP) -- The IOC is finalizing a letter to Olympic athletes reminding them to refrain from demonstrations or political gestures during the Winter Games in Sochi, including any protests against Russia's law banning gay ''propaganda.''

The International Olympic Committee executive board is expected to approve the instructions at its meeting in Lausanne on Tuesday. The letter will then be sent to the national Olympic committees that are sending athletes to the Sochi Games, which run from Feb. 7-23.

The memo will focus on Rule 50 in the Olympic Charter, which states: ''No kind of demonstration or political, religious or racial propaganda is permitted in any Olympic sites, venues or other areas.''

''We will give the background of the Rule 50, explaining the interpretation of the Rule 50 to make the athletes aware and to assure them that the athletes will be protected,'' IOC President Thomas Bach said in an interview with The Associated Press.

''I know from my own experience, this is key,'' added Bach, a former Olympic fencer who won a team gold medal for West Germany in 1976. ''As an athlete you do not want to be confronted in the Olympic Village or the Olympic Stadium with any kind of political controversies.''

The IOC letter comes amid continuing Western criticism of Russia's human rights record and the recently enacted law which bans promotion of ''nontraditional sexual relations'' to minors. The issue has raised questions over what would happen to athletes who wear a pin or patch or carry a rainbow flag to show their support for gay rights.

The charter says the IOC can take action against - even expel - athletes who violate Rule 50, but the committee has said the rule would be ''interpreted and applied sensibly and proportionately.''

''This is about the principles,'' Bach said. ''The principle is to protect the Olympic athletes to be drawn into political controversies. Then, you always have to decide on a case-by-case basis.''

Bach, who was elected IOC president three months ago, met with Russian President Vladimir Putin in Sochi in October. He said Putin assured him there would be no discrimination against any athletes or spectators at the games.

''With regard to the law, he was as clear as he could be,'' Bach told the AP.

The IOC leader met a week ago in Paris with Russian gay rights activists.

''This meeting for us was to listen but also to explain where our responsibility is on the one hand and, on the other hand, where our influence ends,'' Bach said. ''They understood the position now even better and they appreciated having this conversation. We agreed we will keep in contact.''

With the opening ceremony less than two months away, overall preparations for the Sochi Games will be among the top items on the agenda for Tuesday's board meeting. Local organizing committee chief Dmitry Chernyshenko is scheduled to report by video conference.

''They will be ready,'' Bach said. ''There is still some work to do. They know they are under pressure. The last 100 days are almost always the most pressing ones. I have full confidence that they will be ready.''

The IOC board will also hear from Brazilian organizers of the 2016 Olympics in Rio de Janeiro, whose preparations have been dogged by construction delays and concerns over water pollution. Rio organizing chief Carlos Nuzman, an IOC member, is in Lausanne to deliver the update in person.

The board will also consider the status of India's national Olympic committee, which amended its constitution Sunday to avoid becoming the first country expelled from the Olympic movement since South Africa was kicked out more than 40 years ago for its apartheid policies.

Facing an IOC ultimatum, the Indian body agreed to prohibit officials charged with a crime from running for elections. The Indian association was suspended last December for electing tainted officials, notably secretary-general Lalit Bhanot, who spent 10 months in jail on corruption charges related to the 2010 Commonwealth Games in New Delhi.

It will be the first IOC board meeting chaired by Bach, who has been on a whirlwind global tour that included meetings with several world leaders.

Also scheduled Tuesday is a ceremonial handover of the keys to the IOC headquarters from former president Jacques Rogge to Bach. The event takes place at the renovated Olympic Museum, which reopens later this month after nearly two years of work.

After Tuesday's meeting, Bach is taking the executive board on a four-day retreat to the Swiss town of Montreux for a ''brainstorming'' session to review a wide range of issues, including possible changes to the sports program, bidding process and age limit.
