LONDON, Dec 6 (Reuters) - Britain's foreign minister David Cameron will underline the importance of support and humanitarian funding for Ukraine during his first visit to Washington since he assumed his post last month, the UK foreign office said on Wednesday.

The former prime minister will travel to the United States to reaffirm both the strength of Britain's relationship with Washington and London's continued support for Ukraine against Russia's invasion.

The U.S. Congress has approved more than $110 billion for Ukraine since Russia's February 2022 invasion, but has not cleared any more funds since Republicans took control of the House from President Joe Biden's Democrats in January.

Last month, Cameron used his first trip abroad to meet Ukrainian President Volodymyr Zelenskiy in Kyiv.

"The Foreign Secretary has announced a new winter humanitarian response package of 29 million pounds ($36.52 million) for Ukraine and will bolster support with a further 7.75 million pounds ($9.76 million) for humanitarian activities," the foreign office said in a statement.

It comes as Britain is set to target military and foreign suppliers exporting equipment and parts to Russia, among dozens of individuals and groups, through a series of sanctions.

The foreign office said that in Washington Cameron would also discuss the ongoing conflict in the Middle East and getting humanitarian aid to those affected in Israeli-besieged Gaza.

“We also stand united in the Middle East, working together to ensure long-term security and stability in the region, and in responding to the challenges posed by China,” Cameron said.

Britain and the United States can work towards a long-term two-state solution which allows both Israel and the Palestinians can co-exist in peace, his office said.
