* Exporters mixed, market to tread water

TOKYO, July 5 (Reuters) - Japan’s Nikkei was little changed on Friday morning as investors kept to the sidelines before the release of a key U.S. jobs report, while oil and mining shares underperformed after oil prices fell on global growth concerns.
The Nikkei share average was flat at 21,696.57 in midmorning trade. For the week, the index has gained 2% after a Sino-U.S. trade truce sparked hopes the two warring sides could make progress in long-drawn out negotiations.
With U.S. markets closed for a national holiday on Thursday, trading remained thin.
Investors are waiting on the U.S. jobs report due out later in the day, which could determine if the Federal Reserve cuts rates later this month or delays such a move to its next meeting.
The ADP National Employment Report, which comes ahead of the more comprehensive monthly nonfarm payrolls data, showed U.S. private employers added 102,000 jobs in June, well below economists’ expectations.
“Since the ADP number was bad, the market expects the jobs report to be sour, but investors would rather wait till next week to trade as jobs data can provide surprises at times,” said Nobuhiko Kuramochi, a strategist at Mizuho Securities, adding that trading will likely be thin throughout Friday.
Exporters were mixed, with Advantest Corp rising 1.1%, Panasonic Corp falling 0.4% and Toyota Motor Corp was up 2%.
Mining and oil shares lost ground after crude oil prices fell on concerns over the outlook for global economic growth.
Inpex Corp dropped 1.5% and Japan Petroleum Exploration Co fell 0.4%, while Idemitsu Kosan shed 0.6%.
The broader Topix was flat at 1,589.91. Declining issues outnumbered advancing issues 1,160 to 858. (Editing by Shri Navaratnam)
