Suppress space between Chinese and Roman typeface in XeLaTeX

Question

When the Roman characters [a-z0-9] and Chinese characters alternate in XeLaTeX, a space is automatically entered between the two types of character. For example, both Abcde我fg and Abcde 我 fg produce:

Ordinarily, it is stylistically correct to include these spaces, but my question is whether there is a straightforward way to suppress them if I choose to for certain reasons.

(I am using the packages xeCJK and fontspec.)

Answer 1

The \CJKsetecglue command sets the separation character between Chinese and English blocks of text, the default being \CJKsetecglue{ }. So a simple \CJKsetecglue{} should do the trick.
