Why is Western punctuation used in Chinese writing? In Chinese writing full width versions of Western question marks and commas are used.

I've read that:


  [...] the concept of modern standard punctuation was adapted in the
  written language during the 20th century from Western punctuation
  marks. Before that, the concept of punctuation in Chinese literature
  existed mainly in the form of Judou, a system of punctuation marks
  denoting stops and pauses, though many works of poetry and prose, as
  well as nearly all calligraphic works, omitted Judou marks, for in
  most occasions, it was not necessary to understanding meaning.

But why then was the Western way of writing punctuation imported to Chinese writing?

It must have worked perfectly good without them? or was there some gain in starting to use Western punctuation in Chinese?

Classical Chinese has a punctuation system of its own. However, this system is rarely used. The method to read Classical Chinese without punctuation was taught in elementary schools in the past, but it was still too difficult for common people to understand. You may know that Chinese is an isolating language, which means morphemes are quite sequence-sensitive. Even a simple phrase can have quite a few different meanings. In Modern Chinese, this appears even more often.
Examples:
是你 (It) is you
是你。 It is you.
是你？ Is it you?
哼！是你？ Hmph! Is it you? (contempt)
During the late 1910s, there is a movement called New Culture Movement, and a major goal of it is to teach everyone to read and write. The Classical Chinese was too hard for people to read, and lacking punctuation is one of the difficulties. On 29 November, 1919, Ma Yuzao and other 5 person submitted a proposal of calling for using modern punctuation system, which mixed classical and Western punctuations (according to Guan Xihua, 2002). Outline of History of Chinese Philosophy by Hu Shi is the first work applying this punctuation system.  
The reason of adapting a "Western" punctuation system is to make reading texts easier, especially for those who is learning reading for the first time. Since the using of new punctuation system, Baihuawen, or Modern Chinese was popularized quite rapidly.
