Joe Biden will speak to Volodomyr Zelenskyy directly about long-range missiles later this month, according to his national security adviser.
Speaking remotely at a conference in Kyiv, Jake Sullivan said the matter of whether Ukraine will be given permission by Western countries to use their weapons to launch attacks deep into Russia was the subject of "intense consultations" among allies.
He said Mr Biden would speak to the Ukrainian president about the weapons and about a "substantial" new aid package Washington has been working on.
Mr Zelenskyy has said he wants to present Mr Biden with a "victory plan" during their next talks, which he believes will force Russia to end its war.
