BELGRADE, Dec. 17 -- Chinese Premier Li Keqiang held Wednesday a flurry of meetings here with Central and Eastern European (CEE) nations' leaders, particularly highlighting interests in infrastructure cooperation.

The meetings were held a day after the third leaders' meeting of China-CEE countries in Belgrade.

When meeting his Hungarian counterpart, Viktor Orban, Li said China is willing to maintain close coordination with Hungary and other related parties to speed up the construction of the Hungary-Serbia railway, as well as the China-Europe land-sea express passage.

Earlier on Wednesday, China, Serbia, Hungary and Macedonia agreed to build the express line, which links the Greek port of Piraeus in the south and the Hungarian capital of Budapest in the north, stringing the Macedonian capital of Skopje and Serbia's Belgrade.

Pledging closer cooperation in finance, investment and agriculture areas, Li said China will encourage Chinese companies to invest in Hungary.

He also expects Hungary to provide sound policy and stable business environment for Chinese companies, and simplify visa procedures and facilitate work permit process for Chinese workers.

For his part, Orban hailed the fruitful bilateral cooperation, saying Hungary will well implement cooperation documents and expand cooperation in various areas with China.
