Nomura, in a note Wednesday, advised taking money off the table in China's market.
"We are nearing the point where things are as good as they get for the first half of 2016: China's growth is stabilizing, so is the renminbi exchange rate to the U.S. dollar and capital outflows, while consensus forecasts show low likelihood of a June Fed rate hike," the Nomura analysts said.
"In coming months, rising default among private and state-owned enterprises credit and closure of zombie companies as part of supply-side reforms, could raise headline risk," they added.
Japanese stocks extended gains from the previous session on the back of a relatively weaker yen, with the benchmark advancing 32.10 points, or 0.19 percent, to 16,906.54, having been up more than 1 percent earlier.

In the afternoon local time on Wednesday, after Japan's market close, the yen retraced all of its overnight declines, with the dollar/yen pair trading at 108.80, a 0.34 percent drop from its previous close.
Stephen Innes, a senior foreign exchange trader at OANDA, said, "I think we are starting to see pricing of speculative shorts [on the yen] for a few reasons."
"The market didn't break below the key 107.50 handle on Monday and gradually found support as oil prices started to stabilize," Innes explained in a note. "Add in the backdrop of higher U.S. yields from the buoyant Dow and a resurgent Nikkei."
Major Japanese exporters closed mixed, with shares of Toyota down 0.65 percent, Nissan down 0.97 percent, Honda down 0.91 percent and Sony adding 3.9 percent. A strong yen is a negative for exporters, as it reduces their overseas profits when converted to local currency.
Moreover, many of these exporters were recently affected by the multiple earthquakes that hit the south of Japan late last week.

Crude prices were likely weighed by news that Kuwaiti oil workers ended their three-day strike, according to a report from Reuters that said a trade union posted a statement about the end of the strike on Twitter on Tuesday. The strike had temporarily cut the OPEC member's crude production to as little as 1.1 million barrels per day from about 3 million, said Reuters.

The gains in resources stocks came after BHP issued guidance before market open; the miner cut its guidance for fiscal 2016 iron ore production by 10 million tonnes to 260 million tonnes, pointing to adverse weather and the initiation of an accelerated rail network maintenance program. BHP's guidance comes just a day after Rio Tinto cut its 2017 production guidance from its Australian iron ore mines.
