Ukrainian President Volodymyr Zelensky plans to make a major tour across Asian countries, while his visit to the United States is also being discussed.

Deputy Head of the President's Office Ihor Zhovkva said the final list of countries the president will visit is now being formed.

According to the official, the list may include China, South Korea, Indonesia, and other destinations.

"Negotiations are underway through diplomatic channels, but as of now, it is impossible to name the exact date of the visits for objective reasons – unfortunately, the Asian region, like all other regions of the world, periodically suffers from coronavirus," Zhovkva said.

He added a number of agreements had already been prepared, as well as promising projects for the development of trade and attracting investment to Ukraine.

Also, the preparations for Zelensky's visit to the United States are underway. Contact has already been established with the new administration of President Joe Biden. Ukrainian Foreign Minister Dmytro Kuleba and U.S. Secretary of State Antony Blinken earlier spoke over the phone.

"Work continues not only with the State Department, but also the White House," Zhovkva added.

He said a phone talk was being set up for the leaders of Ukraine and the United States.

"Of course, such a conversation will take place. I would not be dramatizing – I would not count down days, minutes or hours. It will happen, as well as the exchange of visits," the diplomat said.

Zhovkva noted the issues of political support were on the agenda, as well as Washington's wider engagement in negotiations on a peaceful settlement in Donbas and the end of Crimea occupation. Issues of economic cooperation have also been discussed.
