Russian Federation expects to host about one million foreigners at the World Cup matches.
Thousands of soccer fans from 31 countries are traveling to the World Cup in Russian Federation that kicks off on Thursday with an opening ceremony in the capital followed by a match between the host team and Saudi Arabia.
Russia's head of parliament's committee for families Tamara Pletnyova said on Thursday that when Russian women marry foreigners, the relationships end badly and women are stranded overseas or in Russia but unable to get their children back.
While Pletnyova wants to protect women from the possible burden of single parenthood, she also argues it would be better if children were born to parents of the same race or nationality.
Children who are mixed-race are likely to be brought up in one-parent families, she warned. "I am no nationalist but nevertheless".
Asked if the World Cup could cause a spike in Russia's birth rate - a key goal for President Vladimir Putin - Pletnyova replied: 'We should be giving birth to our own children'. They have to stay here with mothers'.
Urging women to marry "Russian citizens" instead, she said that children risked being "abandoned and just left with their mother" or being taken overseas by their fathers.
"Even if they marry, they move her overseas, then she does not know how [to return] from there", Pletnyova, who is known for her conservative remarks, told the Govorit Moskva (Moscow Speaks) radio station on Wednesday. "Then they come to me in the committee, these crying girls, because the child has been shipped away, taken and so on". "I would like people to get married based on love in our country, regardless of which ethnicity, [to] Russian citizens who would build a good family, live in harmony, have children, and raise them".
Pletneva previously criticised the #MeToo campaign against sexual harassment, tentatively spreading in Russian Federation.
"Those who get harassed are probably the ones who want it themselves and give the occasion for it", she said in March, claiming that introducing laws in Russian Federation for the offense is "excessive".
