Asian stocks slipped from their six-month highs on Friday due to uncertainty over when and where the US-China trade agreement was signed.
Global stocks rose with news of the two countries agreeing to abolish tariffs in the phase one trade agreement.
But the market lost its gains in Asian trading hours with a report that one of Trump advisers said there was no special agreement over tariff elimination.
The MSCI index fell 0.2%.
Japan's Nikkei, which had hit 13-month highs earlier in the day, lost 0.05%.
Chinese stocks remained stable with a 0.4% increase in the blue chips Index.
