The Nikkei 225 average rose 53.26 points, or 0.26 percent, to end at 20,719.33, a level unseen since Dec. 19. On Friday, the key market yardstick jumped 263.80 points.

The Nikkei gained over 220 points briefly on hefty purchases in early trading before being pressured by profit-taking, market sources said.
Hiroaki Kuramochi, chief market analyst at Saxo Bank Securities Ltd., said Monday’s rise came as U.S. equities continued to gain Friday on hope for progress in U.S.-China trade talks.
But the Tokyo market’s topside grew heavy in the morning after Bloomberg reported that the United States and China were making little progress in their trade negotiations on intellectual property protection, Kuramochi pointed out.
The market met with “selling of export-oriented names and futures-linked selling” following a pause in the yen’s weakening against the dollar traced to the news report, he said.
“Selling emerged after the Nikkei approached 21,000,” said Yoshihiko Tabei, chief analyst at Naito Securities Co.
Tabei suggested that the Nikkei would unlikely to rise above the threshold until players see the results of the Bank of Japan’s two-day monetary policy meeting that ends Wednesday and two days of ministerial trade talks between Washington and Beijing that start Jan. 30.
