PARIS — Secretary of State John Kerry said on Tuesday that the United States and Russia had agreed to share more intelligence on the Islamic State, as he sought to lay the basis for improved cooperation with Moscow.

Just six months ago, Obama administration officials suggested that their goal was to isolate President Vladimir V. Putin following Russia’s decision to annex Crimea and provide military support to separatists in eastern Ukraine.

But Mr. Kerry made it clear that he would welcome expanded cooperation with Mr. Putin after a meeting here with Sergey V. Lavrov, the Russian foreign minister.

While nobody on the American side said the United States was undertaking another “reset” — the term the Obama administration used to describe its early attempt to improve ties with Russia — the tenor of Mr. Kerry’s comments suggested that the State Department was pursuing a new tack.
