BEIJING, Sept. 12 (Xinhuanet) -- Russia wishes the six-party talks, which resumes Tuesday, a success, said Alexander Alexeyev, head of the Russian delegation to the fourth-round six-party talks, when he arrived at the Beijing Capital International Airport Monday.

    He said the Russian side would try its best and hoped that all the other parties could make joint effort for the adoption of a common document.

    The first phase of the talks was "fruitful," however, it was hard to predict the result of the upcoming second-phase negotiation, Alexeyev said.

    According to media reports, Alexeyev said before leaving Moscow for Beijing earlier Monday all parties were "optimistic" about the prospect of the current-round talks and hoped differences could be ironed out.

    The Korean Peninsula nuclear issue could not be solved in one day and the negotiation might be a rather long process, the Russian deputy foreign minister said.

    The Democratic People's Republic of Korea (DPRK) has the right to develop its civilian nuclear capacity and can expect cooperation with other countries if it returns to the nuclear Non-proliferation Treaty, Alexeyev said earlier in Moscow, quoted by JoongAng Ilbo daily newspaper of the Republic of Korea (ROK).

    The Russian delegation was the first to arrive for the talks. The other foreign delegations, from the DPRK, the United States, the ROK and Japan, are expected to come soon.

    The five countries and China, the host country, began the fourth-round six-party talks on July 26 and reached a consensus on a number of issues during their 13 days of discussions on the Korean Peninsula nuclear issue.

    But the negotiators took a recess on Aug. 7 without an agreement on the much expected common document mainly because the US rejected the DPRK's demand for the right to a civilian nuclear program. Enditem
