However, considering layout of the states used in the exercise, as well as their climate and terrain, the intent could be a preparation for an invasion of Iran and a Middle East-wide war.
Russian Deputy Prime Minister Igor Shuvalov made the announcement on March 28 at an international forum in China, saying President Vladimir Putin himself had made the decision for Russia to participate, according to RIA Novosti.
Russia is the latest in a string of countries, including many of the United States' closest allies in Europe and Asia, to announce plans to join the bank ahead of a March 31 deadline to become a charter member.
In recent days, Great Britain, Germany, France, Italy, and South Korea have all said they intend to join the $50 billion bank, which would be used to fund infrastructure improvements, like new roads and rail lines, in Asia.
The offensive to retake the Iraqi city of Tikrit from the Islamic State of Iraq and the Levant (ISIL) has restarted, the Pentagon said.
The announcement came after two days of US-led coalition air strikes and the withdrawal of Iranian-backed militias from fighting.
A US spokesman called the departure of three Iranian-backed militia groups a "welcome" development, but some militias said they had withdrawn in protest at US involvement.
Colonel Steve Warren said there were three air strikes on Friday in support of the operation in Tikrit, and even without the Shia militias, about 4,000 Iraqi troops and Shia volunteer fighters were taking part in the offensive, which he said was "enough combat power to get the job done."
"Iraqi Security Forces are beginning to maneuver into the city, in an effort to push ISIL out of Tikrit," Warren told reporters at a Pentagon briefing.
The Pentagon estimated the number of ISIL fighters still holding the centre of Tikrit to be "in the hundreds".
The legislation, officially dubbed the "Legal Workforce Act" (H.R. 1147), is ostensibly aimed at preventing illegal immigrants from obtaining jobs in the United States. Among the most troubling elements highlighted by critics, though, is that the bill would purport to mandate a national ID card for every American as a condition of working. It would also force every employer in America to purchase and use so-called "E-Verify technology" to check with Washington, D.C., as to whether potential employees have government permission to work. Finally, it would create a massive federal database containing sensitive data on virtually every person in the country - a database that could easily be expanded to include even more information.
