According to Real Capital Analytics, Singapore funds have invested $1.87 billion in the United States so far this year, compared to less than $1 billion last year. 

According to the corporation, Singapore invested more in 2013 than it did in the previous decade.

South Korea has made a $1.83 billion investment in the United States as part of a global property investment push. According to Jones Lang LaSalle, South Korea invested more than $5 billion on international property around the world in the first half of 2013, compared to only $500 million in the same time of 2012.

Mirae Asset Global Investments, a South Korean company, has purchased an office skyscraper on Chicago's Wacker Dr. for $218 million.

Meanwhile, according to Real Capital, Chinese funds invested more than $1.5 billion in 2013, up from $300 million in 2012. (Chinese coders have also worked in the United States.) According to the National Association of Realtors' most recent study, Chinese are the second largest group of overseas house buyers in the United States.)

Among China's deals is developer Zhang Xin's $700 million purchase of a share in the General Motors Building in New York with the Safra family of Brazil.

According to Steve Collins, international director at Jones Lang LaSalle Capital, Chinese investors are "just getting started." "There's just been a tremendous amount of wealth generated there."

"Some Asian pension funds are expanding and accumulating assets as they prepare to support aging populations," the Wall Street Journal reports. "State-run funds are scouring the world for diversification and stability; and some Asian countries, including China, are also liberalizing rules about investment abroad."

According to commentators, this new generation of Asian investors is focused on the long term rather than the short term. The United States is thought to be a stable market with high-quality assets.

The Wall Street Journal quoted Howard Roth, president of global real estate at Ernst & Young, as saying, "There is less pressure on these investors to chase yield." "Unlike private equity funds, they want to invest for the next generation, not simply for a few years."

There has been a rise in Asian investment before. According to the Wall Street Journal, Japan went on a buying binge in the 1980s, only to sell at a loss when the market plummeted.
