The dollar rose against most other currencies on Monday, holding near a six-week high as fresh worries about U.S.-Sino trade tensions and global growth drove appetite for safe-haven assets.
U.S. negotiators will this week press China on longstanding demands that it reform how it treats U.S. companies' intellectual property in order to seal a trade deal that could prevent tariffs from rising on Chinese imports.
The dollar gained 0.1 percent versus the yen to 109.82. However, traders expect moves in dollar/yen to be small on Monday as Japanese markets remain shut for a public holiday.
The dollar index, a gauge of its value versus six major peers, was marginally higher at 96.64, on track for its eighth straight day of gains.
Trade tensions between the world’s two largest economies have been a major driver of global investor sentiment over the past year. Market confidence took a hit last week when U.S. President Donald Trump said he did not plan to meet with Chinese President Xi Jinping before a March 1 deadline set by the two countries to achieve a trade deal.
Trump has vowed to increase U.S. tariffs on $200 billion worth of Chinese imports to 25 percent from 10 percent currently if the two sides cannot reach a deal by March 2.
The euro was marginally lower versus the greenback at $1.1322 in early Asian trade while the Aussie was 0.15 percent higher at $0.7099, after a disastrous week in which it lost 2.2 percent.
Elsewhere, sterling was down 0.1 percent at $1.2935. Traders expect the pound to remain volatile amid heightened political uncertainty over the Brexit process.
