MOSCOW, June 24 (Xinhua) -- Russian President Dmitry Medvedev seemed to have much fun during the first leg of his current visit to the United States. While in California, he opened his official account in Twitter, received a brand-new iPhone 4, visited Russian Varyag cruiser and mingled with the Russian-speaking students in Stanford University.

However, the Russian president's trip to America was definitely not for high-profile socializing only.

ONE BILLION DOLLARS FOR SKOLKOVO START-UP

The Russian leader secured one billion U.S. dollars of investment with Cisco company for his favorite "child" - the Skolkovo hi-tech project. Medvedev visited the headquarters of other hi-tech champions like Apple and Yandex Labs where the boyish-looking Russian leader had face-to-face chats with their respective chiefs, Steve Jobs and Arkady Volozh.

"Here in the Silicon Valley the most valued thing is socializing, but for business, not idle one," the Russian president said. In his new Twitter blog Medvedev shared his dream, that is, to create in Russian Skolkovo the similar environment he witnessed in the Silicon Valley.

Medvedev noted that Russian "Silicon Valley" would not just emulate its Californian original. He recognized it, though, that such an environment could not be created by order.

NOT BY HI-TECH ALONE

Despite the predominantly "technocratic" essence of his visit and focusing on the building momentum behind his innovations and modernization attempts, Medvedev was unable to avoid some purely political issues.

Speaking in Stanford University, Russian president promised to protect the private property in his country, and fight against the widespread corruption, which was one of the main fears for foreign investors.

"I see my task as a president in strengthening the judicial authority and create a judicial system that really works and citizen can trust to. Good laws alone will not fix the situation," Medvedev told the students as quoted by Russian media.

"Russia is striving to become an open country, ready for partnership with everyone who is ready for joint work," Medvedev said, who also did not rule out the possibility for him to run for a second term in office.

"If I have support," as he put it.

FASTFOOD DIPLOMACY

In Washington, D.C., the American host kept making Medvedev's visit a sort of Disneyland VIP holiday, including an unexpected drive-in to a hamburger restaurant in Arlington, Virginia for a private lunch and narrow-format talks.

Thursday meeting was the seventh between Barack Obama, 48, and Medvedev, 44, both lawyers by training.

Washington also made "a present" for Moscow's top visitor on the eve of his arrival. The U.S. State Department announced on Thursday that a long-standing foe of Kremlin, Chechen warlord Doku Umarov, has been included into the U.S. wanted terrorists list.

Russian Foreign Ministry reacted immediately, describing that decision as "a result of strengthening anti-terrorists partnership between our countries."

Amidst these mutually petting gestures, the two leaders has discussed the pace of ratification for the new nuclear disarmament treaty, situation in the Middle East, the Korean Peninsula, Kyrgyzstan and Afghanistan, Iranian nuclear program, U.S.-Russian bilateral cooperation and Russia's bid for the World Trade Organization (WTO)

The latter was, likely, the least entertaining part of Medvedev 's agenda, despite Obama's policy of making concessions to Russia in exchange for Kremlin cooperation on the U.S. foreign policy goals.

Russian president hinted earlier that he would expect the Obama administration to support Moscow's 17-year-long claim to joint WTO. Russia, the largest economy outside the WTO, has repeatedly accused Washington of holding up its accession.

U.S. responded by noting that Moscow delayed its bid by asking to join with Kazakhstan and Belarus as a single entity. Also, Washington demanded that Moscow improve the protection of intellectual property rights.

The U.S. trade with Russia through the first four months of this year rose 27.4 percent compared with the same period last year, to 8.48 billion U.S. dollars, according to the Bloomberg news agency.
