The agreements marked a new beginning in the relationship between the two countries, which had come to a standstill under Ukraine's previous president Viktor Yushchenko.
Apart from boosting their political relationship, the two sides also signed 12 agreements on technology, infrastructure and credit cooperation, including programs of cooperation in exploring and using space for peaceful purposes in 2011-2015.
An agreement was also signed securing China's credit support to a 30-km railway project and construction of auxiliary facilities for an airport in Ukraine's capital, Kiev, which will take three years before completion. The railway project, contracted to a Chinese firm, will cost $950 million and construction will begin next year.
The two countries also agreed to push forward trade deals to approximately $10 billion in 2012, about five times that of 2009.
China has always attached importance to ties with the East European country, which bridges Asia and Europe.
Strategically located it has strong cultural and political links with the Commonwealth of Independent States (CIS) as well as trade links with the European Union (EU).
Good relations with China were established under a former president, Leonid Kuchma. However, during the reign of the "Orange team", led by Yushchenko, Sino-Ukrainian relations deteriorated.
In April, Yanukovych, who became Ukraine president in February, and Hu met in Washington and agreed to the Ukrainian president's visit to China.
The visit, which local papers are describing as "epochal", "historical", or, "extraordinary", has been viewed by analysts from both countries as a strategic move both politically and economically for the two nations to secure their ties in a changing regional landscape.
"Ukraine is the second largest country of the CIS. Geographically, it serves as China's gateway to Europe. Therefore the strategic location of Ukraine is significant," said Wang Lijiu, researcher of the institute of Russia studies under the China Institute of Contemporary International Relations.
