US President Donald Trump and Russian President Vladimir Putin had a previously undisclosed conversation during a dinner for G20 leaders at a summit earlier this month in Germany  nike air vapormax plus scontate , a White House official said.

The two leaders held a formal two-hour bilateral meeting on July 7 in which Trump later said Putin denied allegations that he directed efforts to meddle in the 2016 US presidential election.

Trump's interactions with the Russian leader were scrutinized closely because of those allegations, which have dominated his first six months in the White House, and Trump's comments as a presidential candidate praising the former KGB spy.

Trump and Putin first met at the G20 during a gathering of other leaders  nike air max 98 supreme saldi , which was shown in a video.

They later held the bilateral meeting, which was attended briefly by a pool of reporters.

In the evening, both men attended a dinner with G20 leaders.- Putin was seated next to US first lady Melania Trump.

The US president went over to them at the conclusion of the dinner and visited with Putin  nike air max tn ultra saldi , the official said.

That conversation had not been previously disclosed.

"There was no 'second -meeting' between President Trump and President Putin, just a brief conversation at the end of a dinner. The -insinuation that the White House has tried to 'hide' a second meeting is false, -malicious and absurd  nike air max 97 uomo saldi ," the official said.

In a tweet late on Tuesday, Trump said, "Fake News story of secret dinner with Putin is 'sick.' All G20 leaders  nike air max 97 saldi , and spouses, were invited by the Chancellor of Germany."

News of the conversation, first reported by Ian Bremmer  nike air max 270 saldi , the president of political risk consultancy Eurasia Group, could raise renewed concern as Congress and a special counsel investigate allegations by US intelligence agencies that -Russia interfered to help Trump, a -Republican  nike just do it air force saldi , win the presidential election.

Trump says there was no collusion and Russia denies interference in the election.

Bremmer said Trump got up from his seat halfway through dinner and spent about an hour talking "privately and animatedly" with Putin, "joined only by Putin's own translator."

The lack of a US translator raised eyebrows among other leaders at the dinner, said Bremmer  nike just do it scarpe bianche , who called it a "breach of national security protocol."

GUIYANG， July 3 (Xinhua) -- Installation was completed on the world's largest radio telescope on Sunday morning as the last of 4，450 panels was fitted into the center of the big dish.

Hoisting of the last triangular panel to the reflector， which is the size of 30 football fields， began at 10:47 a.m. and lasted about an hour. It was a landmark step for the telescope's planned launch of operations in September.

About 300 people， including builders， experts， science fiction enthusiasts and reporters， witnessed the installation at a karst valley in Pingtang County in the southwestern province of Guizhou.

"The telescope is of great significance for humans to explore the universe and extraterrestrial civilizations，" said Liu Cixin， a renowned science fiction writer， at the site.

"I hope scientists can make epoch-making discoveries，" said Liu， who won the 2015 Hugo Award for Best Novel.

Scientists will then begin debugging and trial observation of the Five-hundred-meter Aperture Spherical Telescope (FAST)， said Zheng Xiaonian， deputy head of the National Astronomical Observation (NAO) under the Chinese Academy of Sciences， which built the telescope.

The project has the potential to search for more strange objects to better understand the origin of the universe and boost the global hunt for extraterrestrial life， said Zheng.

Zheng said the radio telescope will be the global leader for the next 10 to 20 years.

In the first two or three years after its completion， the telescope will undergo further adjustment， and during that period Chinese scientists will use it for early-stage research. After that， it will be open to scientists worldwide， said Peng Bo， director of the NAO Radio Astronomy Technology Laboratory.

Scientists can also carry out remote control and observation in other cities such as Beijing， more than 2，000 kilometers from the telescope site， said Peng.

Upon completion， the telescope will dwarf Puerto Rico's Arecibo Observatory， which is 300 meters in diameter. It will also be 10 times more sensitive than the steerable 100-meter telescope near Bonn， Germany， he said.

"Most of the technology and materials are domestically made，" said Wang Qiming， chief technologist of the FAST project.

Among the 7 FAST receivers， five were domestically made and another two were co-produced by Chinese， Australian and American institutions.

Work on the 1.2-billion-yuan (180 million U.S. dollars) FAST project began in 2011.

EYE ON THE SKY

Radio telescopes have made major astronomical discoveries， such as pulsars， quasars and cosmic microwave background radiation. Among the 10 Nobel Prizes in physics awarded for discoveries related to cosmology and space， six were attributed to radio telescopes.

"As the world's largest single aperture telescope located at an extremely radio-quiet site， its scientific impact on astronomy will be extraordinary， and it will certainly revolutionize other areas of the natural sciences，" said Nan Rendong， chief scientist with the FAST Project.

FAST will enable astronomers to get a jump-start on many scientific.  Cheap Jerseys    Cheap Jerseys From China    Cheap Jerseys From China    Wholesale Jerseys China    Cheap NFL Jerseys    Cheap NFL Jerseys    Wholesale Jerseys Free Shipping    Cheap NFL Jerseys    Wholesale Football Jerseys    Wholesale NFL Jerseys Free Shipping
