TREASURIES-US 30-year bond trades 3 points lower in price

NEW YORK, Jan 29 (Reuters) - The U.S. 30-year bond traded more than three points lower in price on Thursday, weighed by concerns over pending debt supply and Vice President Joe Biden's comment that the U.S. will insist China abide by international trade rules.

Debt investors are worried that recent comments from the new U.S. administration may spur China to curtail its purchases of new U.S. government debt or even move to sell some of its vast Treasuries holdings.

The 30-year bond US30YT=RR was trading over three points lower in price for a yield of 3.58 percent from 3.42 percent late on Wednesday, while the benchmark 10-year Treasury note US10YT=RR was 1-16/32 lower for a yield of 2.84 percent from 2.67 percent.
