Shares in Asia mostly gained Tuesday as market sentiment improved ahead of the phase one trade deal signing between China and the U.S. later this week. Optimism rose further after Washington said Beijing was no longer a currency manipulator.

The Nikkei 225 climbed 0.51% and the Topix index was flat after Japanese markets returned from a public holiday on Monday. Shares of technology conglomerate Softbank rose 3.22%.

In South Korea, the Kospi gained 0.38%.

China’s yuan-denominated imports from the U.S. rebounded in November and December, Reuters reported citing data from China’s customs released on Tuesday. It was the first time that its exports went up since March last year.

In particular, China’s soybean and pork imports from the U.S. significantly rebounded in December. Washington has demanded that Beijing buys more agricultural goods from the U.S. as part of their phase on trade deal — the signing of that agreement is set to happen on Wednesday in Washington. The deal is also expected to involve some rollback of tariffs.

Ahead of the signing, the U.S. removed China from the currency manipulator list on Monday — more than five months after the U.S. Treasury put the country on it, saying that Beijing has been keeping the yuan artificially weaker.

Even before it was removed from the list, the yuan had been appreciating and jumped to a five-month high last week.

On Monday, the Chinese currency strengthened further to the level below 6.90 — which was the strongest level to the dollar since Aug. 1. The offshore yuan was at 6.8727, from last week’s high of 6.9775. The onshore yuan was last at 6.8718, as compared to a high of 6.9786 last week.
