(Corrects reason for shipping sector's rise in 10th paragraph)
* Nikkei has risen 2.3 pct for the week so far
* Shippers worst performer, hit by profit-taking
* Financials pull back from recent gains
TOKYO, Feb 22 (Reuters) - Japan's Nikkei snapped four straight days of gains on Friday morning as weak U.S. economic data dampened sentiment, though the selling was contained by more signs of progress in U.S.-China trade talks.
The Nikkei share average dropped 0.3 percent to 21,391.99 in midmorning trade, though it is still up 2.3 percent for the week so far.
The U.S. Commerce Department said new orders for key U.S.-made capital goods unexpectedly fell in December.
The Philadelphia Federal Reserve's gauge of U.S. Mid-Atlantic business activity also declined in February to its weakest level since May 2016, while another report showed U.S. existing home sales dropped last month to the lowest level since November 2015.
"Weak U.S. economic indicators are worrying the market, but hopes for more progress in U.S.-China trade talks are supporting the mood," said Shoji Hirakawa, chief global strategist at Tokai Tokyo Research Institute.
Hirakawa said that since the Nikkei breached an immediate resistance level of 21,500 on Thursday, investors are looking out for the next resistance level at 21,800.
Focus in global markets is also squarely on high-level talks between U.S. and Chinese trade negotiators in Washington, with little more than a week left before a U.S.-imposed deadline for an agreement expires, which would trigger higher tariffs.
Reuters reported exclusively on Wednesday that the two sides were drafting language for six memorandums of understanding on proposed Chinese reforms, progress that had helped to lift investor sentiment.
Friday's losers included financial stocks such as banks and brokers, which gained recently. Mitsubishi UFJ Financial Group dropped 1.6 percent and Sumitomo Mitsui Financial Group shed 1 percent, while Nomura Holdings fell 1.4 percent.
The shipping sector shed 2.2 percent and was the worst sectoral performer as investors took profits after the sector climbed the previous day. Mitsui OSK Lines dropped 2.2 percent and Kawasaki Kisen slumped 2.7 percent.
Bucking the weakness, Kobe Bussan, a retailer for food ingredients for business use, gained as much as 5.3 percent to a record high after its same-store sales in January rose 9.9 percent on the year.
The broader Topix declined 0.4 percent to 1,606.90. Declining issues outnumbered advancing ones 1,452 to 570. (Editing by Shri Navaratnam)
