1. The world is in transition between two world languages, English and Chinese. Both are very hard for non-native speakers to learn (and not all that easy for native speakers who believe there is a "correct" form of their language). This is a perfect time to push for an alternative that's far, far easier to learn than either.
2. Mondlango was created primarily by Chinese thinkers who built on Esperanto (a primarily European conlang) while recognizing the importance and usefulness of English in the world today. It is the most international conlang that I know of.
The "official"* Mondlango site is a good place to start your googling.
* From here:
Strictly speaking, in the realm of Monda, there are founders and followers, but there is no creator. Most vocabularies in Monda are not arbitrarily created, but are derived from the Indo-European language family (especially from English ). Zamenhof , being the author of Esperanto, was also the vanguard of Monda. Monda was born in July 2002. The major founder of Monda is HeYafu, the other founders are Wangli, Qijiaqin, Luoxinxing, Arbsemo, Kulturo, Chenruihua , Zangyuhai, Niyundong, Zhaozhonghua, Oscar Mifsud , David Curtis , Dominique Kuster , Matthew Martin, J Duke and Daniel Carrera.ETA:
