BEIJING/MOSCOW, Oct 10 (Reuters) - China and Russia will discuss an elusive giant gas deal during Prime Minister Vladimir Putin's visit to Beijing, but a Russian official said on Monday that there were no plans to sign an agreement just yet.
Putin's two-day visit from Tuesday will be his first foreign trip since revealing plans to reclaim Russia's presidency. He could seek to narrow price disagreements that have prevented Russia from signing a 30-year deal to supply China with up to 68 billion cubic metres of gas per year.
Chinese Foreign Ministry spokesman Liu Weimin told a news conference that during the visit, Chinese Vice Premier Wang Qishan would hold a fresh round of energy cooperation negotiations with Russian Deputy Prime Minister Igor Sechin.
But in a further sign that the talks would yield no final agreement on price, Russia's gas export chief, Alexander Medvedev, said he would not be part of formal talks.
Medvedev, chief executive of Russian state-controlled gas company Gazprom's export arm, said he was in Beijing merely to oblige if Chinese officials wished to speak to him.
"It is quite clear that it is not easy to find a solution," he told Reuters by telephone.
The tortuous gas negotiations have been a reminder that, despite frequent professions of brotherly goodwill between Moscow and Beijing, relations are held back by mutual distrust extending back to the Cold War, when border disputes almost erupted in full-fledged war.
Liu did not comment directly on any prospects for a gas agreement. The export chief of Gazprom, the Russian gas supplier, told Reuters last month that the five-year-old negotiations might not end this year.
"Chinese-Russian energy cooperation is an important part of the two countries' strategic cooperation," said Liu.
"The meeting between Deputy Prime Minister Sechin and Vice Premier Wang Qishan will allow more thorough exchanges of views on energy cooperation," he added.
In Moscow, a senior government official said Putin had no plan to sign a gas pricing deal during his visit.
"The signing of the gas pricing deal is not planned at this point," Yuri Ushakov, the government's deputy chief of staff, told reporters.
He said a delegation of officials, experts and energy sector executives, headed by Sechin, was already in Beijing to discuss a wide range of issues, including future gas supplies.
Russia wants to diversify its trade with China, which is expected to grow to $100 billion in 2020 from $59.3 billion in 2010.
"This is very important for us. Our exports are massive but are mainly resource-based. We are not happy with it. We will discuss measures to correct this," he said.
Putin and Chinese President Hu Jintao will discuss Syria after China joined Russia last week to block a proposed U.N. Security Council resolution that Western powers backed to condemn the bloody crackdown there, he added.
Chinese ministry spokesman Liu did not directly comment on the contentious issue of a Chinese national whom Russian authorities last week said faced charges of suspected military espionage.
The Chinese citizen is accused of trying to buy sensitive material on a Russian anti-aircraft missile system while working as a translator, Russia's Federal Security Service (FSB) said, according to the state-run RIA news agency.
It said the suspect was detained in October last year. Prosecutors filed charges of espionage with the Moscow City Court last week.
