Williams was born in Spain to Ghanaian parents and has played once for the Spanish national in a friendly game in 2016.
The 27-year-old is still eligible to represent the Black Stars nonetheless but he feels too attached to his country of birth to play for another national side.
Williams has confirmed that he has received approaches from Ghana to play for the West African side but feels his allegiance lies with Spain.
“I’m grateful to where I grew and became who I am. Ghana tried to convince me, but I was born in Spain, in Bilbao. I won’t ever forget my family roots, but I feel Basque and can’t con anyone. I would be comfortable with Ghana, I’m sure, but I shouldn’t be there,” Williams told The Guardian.
“And my mum knows how people live football there: it’s quite something, and she’d be worried about me.
“My parents are from Accra and I really enjoy going. But I wasn’t born or raised there, my culture’s here, and there are players for whom it would mean more.
“I don’t think it would be right to take the place of someone who really deserves to go and who feels Ghana 100 percent.”
He added: “When my mum’s angry, she swears at us in Ghanaian [language] but we speak Spanish. When my parents came, it was English, but we lost that. I could have a conversation in English but it’s not fluent now,” Inaki added.
“When my grandparents call, I speak to them in Twi. I admire and love Ghana, the culture, food, tradition.”
