In a statement titled The Flag at the US Embassy in Kiev, US Secretary of State Antony Blinken described reopening the diplomatic representative office as an important step. The US flag was raised over the Embassy building in a brief ceremony.
Mr. Blinken said: "We are proud and continue to support the government and people of Ukraine to protect the country".
The US Secretary of State explained that the temporary suspension of operations was necessary for the safety of the Embassy staff, but when it reopened, the Embassy took additional measures to protect staff.
We reaffirm our commitment to the people and government of Ukraine and we hope to fulfill our mission from the US Embassy in Kiev, Blinken said.
Daniel Langenkamp, a spokesman for the consulate, told Reuters that consular activities have been suspended so far and that the US State Department's "travel ban" warning is still in place across Ukraine.
The US State Department official told The New York Post that the US Navy currently does not have members deployed to protect Embassy staff - as is the standard at US embassies elsewhere in the world. However, the Ministry of Foreign Affairs will have a plan to appoint such a protective force.
The Foreign Ministry official added that direct consular services, including those for US citizens and visa services, will remain suspended until further notice.
In recent weeks, several countries have also reopened their embassies in the Ukrainian capital, including Canada, Denmark, the UK, Italy, France and Armenia. On May 17, Israeli Ambassador Michael Brodsky posted a photo of the flag-raising ceremony in Kiev.
The US Embassy in Kiev announced its closure on February 14 - 10 days before Russia launched a military campaign in Ukraine - as US intelligence assessed that Russian President Vladimir Putin was ready to order an attack.

In early April, Russia withdrew troops from northern Ukraine, including areas around Kiev, to focus on capturing southern and eastern Ukraine. But the Ukrainian military this month pushed Russian forces northeast toward the Russian border near Kharkiv, Ukraine's second largest city.
Despite Ukraine's unexpected success, Russia has won a number of victories, including the Ukrainian forces, including members of the Azov battalion, surrendering after three months of stagnation at the Azovstal steel plant in the port city of Mariupol. The move would allow Russia to completely control Mariupol, a city strategically located along the Azov Sea to the Crimean peninsula, which Russia later voted for in 2014.
