China is selling some of its U.S. Treasury bonds.

Although the amount that China sold was small, it was a signal to Washington that Beijing is concerned about the future of the dollar, Agence France Presse reported.

"China is implying to the U.S. more or less, that it should adopt a more pragmatic and responsible attitude to maintain the stability of the dollar," He Maochun, a political scientist at Tsinghua University, told the Global Times.

Many analysts have warned that heavy spending in Washington could lead to inflation, and a decline in the value of the dollar.
