Manufacturing activity in China expanded for a second straight month in December as seasonal demand and signs of progress in trade talks with Washington boosted factories¡¯ output and order books.

China¡¯s official Purchasing Managers¡¯ Index (PMI) was unchanged at 50.2 in December from November, the National Bureau of Statistics said on Tuesday, slightly higher than the 50.1 expected in a Reuters poll of analysts.

It also remained above the 50-point mark that separates monthly growth from contraction.
