Under the ‘Belt and Road’ initiative, as economic and culturalexchanges between Kenya and China deepen, Chinese language is playingan increasingly important role in Kenya’s education system. This paperemploys contrastive analysis theory to explore the challenges faced by Swahilinative speakers when learning Putonghua. The article begins by introducingKenya's multilingual policy and the context of Putonghua teaching in Kenya.Subsequently, the paper provides a detailed comparison of the phoneticsystems of Putonghua and Swahili, including contrasts in their vowel andconsonant systems. Through an in-depth analysis of the phonetic features ofboth languages, the study reveals the complexity of Putonghua’s tonal systemand its rich assortment of consonants, as well as the relatively simple syllablestructure and consonant system of Swahili. The findings indicate that Swahilinative speakers may encounter a range of challenges when learning Putonghua,particularly in achieving pronunciation accuracy, such as adapting to thedifferences between rounded and unrounded vowels and special consonantphonemes in Putonghua. Finally, the paper suggests that Putonghua instructorsshould design specific teaching strategies and exercises to help Swahili learnerseffectively adapt to and master the phonetic characteristics of Putonghua.
