U.S. government debt prices were higher on Tuesday as investors digest fresh economic data, while concerns from overseas remained.
The yield on the benchmark 10-year Treasury notes, which moves inversely to price, was lower at around 2.174 percent, while the yield on the 30-year Treasury bond was also lower at 2.836 percent.
U.S. Vice President Mike Pence reassured Japan of American commitment to reining in North Korea's nuclear and missile ambitions on Tuesday, after warning that U.S. strikes in Syria and Afghanistan showed the strength of its resolve.
Pence arrived in Tokyo from South Korea, where he assured leaders of an "iron-clad" alliance with the United States in the face of the reclusive North, which has conducted a series of missile and nuclear tests in defiance of U.N. sanctions.
Investors also kept an eye on France, as campaigning ramped up ahead of the first round of the presidential election. Left-wing candidate Jean-Luc Melenchon's surge in polls added to investors' worries as it becomes unclear who will win the contest.
