Tokyo stocks inched down Monday on renewed concerns over the dim outlook for US-China trade talks.
The benchmark Nikkei 225 index fell 0.16 percent, or 34.95 points, to close at 21,375.25, while the broader Topix index was down 0.01 percent, or 0.15 points, at 1,572.75.
They had opened higher, extending rallies on Wall Street, as US jobs data eased recession fears while maintaining rate cut expectations.
But the indexes closed in negative territory "as a news report said the Chinese side is cautious about a deal", said Toshikazu Horiuchi, a broker at IwaiCosmo Securities.
The United States and China are scheduled to hold ministerial-level negotiations in Washington later this week.
"But selling pressure was limited as investors are ready to buy on dips," Horiuchi told AFP.
