The best airport in the world, the most lavish food markets ever to be immortalised in a film: for me, Singapore was always a city of superlatives, somewhere between Asian authoritarianism and Western democracy. I was in Singapore once many years ago when I stopped over on the way to my relatives in Vietnam. The British English spoken by the inhabitants, the spotless streets and the architecture ranging from colonial English to hyper modern gave the city an international sophistication which I had not come across in Ho Chi Minh City, Beijing or Tokyo.

I never suspected that this trip would turn out to be a great surprise for other reasons as well. In Singapore of all places, 9,900 kilometres from my home town of Berlin, Germany, a great many people are asking themselves questions similar to my own: what does it mean to feel both Western and Asian at the same time? How do those different cultures fit together? And how do I explain the contradictions within me to others?

First, I spoke about this with the author Parag Khanna, whom I met the day after my arrival at a lunch held by the German Ambassador, Norbert Riedel. Khanna was born in India and grew up in Dubai and the USA. Most recently, he wrote a book about migration called 'Move'. In fluent German, he told me that he moved to Singapore nine years ago with his family because it is the 'capital of Asia'. Normally, it is possible to fly from here very quickly to Delhi, Shanghai or Hong Kong. However, he does not find Singapore to be typically Asian. On the contrary, he enjoys the multicultural environment: apart from the large Chinese community, there is also an Indian and a Malaysian one.

How do I explain the contradictions within me to others?

'Do you have a special relationship with the Indian community because you were born in India?' I asked him. Khanna shook his head. For him as a global intellectual, the particular attraction lies in not committing to one culture, but in overcoming one-sided categories. I could well understand that, because I, too, had often been annoyed when others asked me whether I called myself 'German or Vietnamese'. Sometimes I would answer, 'Neither nor,' and sometimes, 'Both.' For me, both answers amounted to the same thing: an identity which is fluid.

Between closeness and alienation

Bridgette asked me about my attitude towards Vietnam and I told her that I felt the same way about it. The longer we spoke, the clearer it became to me that both of us belong to the Asian diaspora and, therefore, we share an ambivalence: on the one hand, we were familiar with both the Chinese and the Vietnamese culture and the language. On the other hand, we lived in Singapore and Germany, which has shaped us just as much, if not more. Is this feeling of being torn between closeness and alienation simply part of life in the diaspora? Probably.

On the day of my departure, I made a detour to the German European School Singapore. I was taken to a small, but modern library and was surprised to see that 'Wherever You Are' was already on the shelf, catalogued with a light-green label on which 'LIT PHAM' could be read. If someone had told me a year ago that my novel would travel all the way around the world and end up in this library I would have thought this to be utopian. But in this school, which teaches children from more than 66 nations, they were glad to have it, because the story of my main character, Kiều, who cannot pronounce her own name and prefers to call herself 'Kim', is one which many pupils can relate to.

'True home': is there such a thing?

I sat down beside two girls and a boy who had already read the book and wanted to ask me some questions about it. The boy had Vietnamese parents and a German name, but the only home he knew was Singapore. Next to him was a classmate who had grown up in Germany and been living in Asia for years. And next to her was a pupil with a Vietnamese father and a German mother. From their remarks, I heard that they sometimes wondered where their 'true home' was.

'When I was younger, I also struggled with my identity,' I told them. 'But now, I regard having more than one culture and one homeland as a gift. It was the reason why I wrote this book.'  They nodded slowly and I could see their thoughts rattling inside their heads.

As I sank into my seat on the plane that evening and it took off on its route to Berlin, I felt as if I'd been travelling for two months rather than just five days. I still couldn't quite believe it: I'd flown to the other side of the world and met many like-minded people in a foreign country. And I had learned from my readers what was most wonderful about writing. Perhaps that's the magic of travelling: that you learn so much about yourself when you're far from home. I had almost forgotten that in the last two years.
