MOSCOW — Russia's parliament is preparing to debate a measure that would ban adoption of Russian children by Americans, raising the stakes in a dispute with Washington over human rights legislation.

The proposal comes after President Barack Obama signed into law last week a bill that imposes sanctions on Russians deemed to be connected with human rights abuses.

A retaliatory measure that passed its first reading in the Russian Duma last week calls for establishing a blacklist of Americans judged to have violated the human rights of Russians. Officials said that would include those who abuse children adopted from Russia.
