TOKYO (Kyodo) -- Tokyo stocks rebounded Tuesday as fears over a potential trade war eased after the United States suspended planned tariffs on Mexico and Canada for 30 days, but gains were trimmed by concerns about its duties on China.

The 225-issue Nikkei Stock Average ended up 278.28 points, or 0.72 percent, from Monday at 38,798.37. The broader Topix index finished 17.63 points, or 0.65 percent, higher at 2,738.02.

On the top-tier Prime Market, gainers were led by nonferrous metal, textile and apparel and electric appliance issues.

The U.S. dollar strengthened to the lower 155 yen range in Tokyo, as traders sold the yen, seen as a safe-haven asset, after U.S. President Donald Trump decided to delay 25 percent tariffs on imports from Canada and Mexico as the neighboring nations agreed to take steps to address his concerns on border security, dealers said.

At 5 p.m., the dollar fetched 155.32-34 compared with 154.70-80 yen in New York and 155.61-64 yen in Tokyo at 5 p.m. Monday.

The euro was quoted at $1.0311-0312 and 160.16-20 yen against $1.0337-0347 and 160.01-11 yen in New York and $1.0224-0226 and 159.11-15 yen in Tokyo late Monday afternoon.

The yield on the benchmark 10-year Japanese government bond closed at 1.275 percent, its highest level since April 2011 and up 0.030 percentage point from Monday's close. The debt was sold as traders shifted to riskier assets after the tariff delays.

Stocks were bought back after the Nikkei benchmark shed over 1,000 points the previous day, as the pause on tariffs to allow Trump and his counterparts to negotiate boosted sentiment in Toyota and other automakers with production bases in Mexico.

Exporters had suffered heavy selling Monday on concerns their products could become more expensive in the United States and dampen sales in the world's largest economy. Heavyweight semiconductor-related issues also lifted the market after steep losses.

But stocks erased some gains in the afternoon as an additional 10 percent U.S. tariff on China reportedly took effect, raising concerns that Japanese companies operating in China could be affected by a weaker Chinese economy, brokers said.

"The reversal on Canada and Mexico raised hopes that measures on China might be avoided, but in the end it didn't work out," said Makoto Sengoku, senior equity market analyst at the Tokai Tokyo Intelligence Laboratory Co.
