What is the best strategy for customer focus competency if I have customers from different countries with various cultural backgrounds?

I would agree with the provided answers .. variety of helpful opinions

I would add that in such situation you should have different approaches in helping customers because of their backgrounds and cultures, so "multi" options is required.And for example McDonald; It is helping multi cultures and people around the world, and it offers them what they like in respect to their cultures;e.g. Must have Halal meat for Muslim people... Have bacon recipes in non Muslim countries ... etc

It is important for a customer service element to understand that moving their program toward cultural competence requires a personal commitment and significant involvement from the entire staff. Cultural competence is an ongoing process of examination and change, not a goal to be attained once. To move toward cultural competence, staff members will have to contemplate on an ongoing basis what life is like for people different from themselves. Administrators should encourage program staff members to adopt an inquisitive and open-minded attitude toward other cultures.

Every culture has specific values that can be used in treatment, such as the support of extended families and of religious or spiritual communities. By appreciating a client's culture, staff can tap into the most effective treatment strategies, those based on the personal and social strengths of each individual.

The consensus panel believes that the competent handling of diversity is a basic issue underlying good treatment. The empathy and trust that a program's staff needs to practice to move toward cultural competence are an extension of the qualities that make a good counselor.

Build CEE team (Customer Experience Enhancement Team) which will comprise of two set of people, one set of people will be internal team appointed by Company and for other set conduct one competition in that respective market and chose individual from it, who will act like opinion leaders for the target customer market.

We should use them as IDEA cum FEEDBACK bank to formalize our strategy to capture market.

I believe every customer should be treated equally regardless of gender, age, religion, country origin.

However there are other aspects ... you do not serve a muslime alcohol  nor should consume you when you are in a restaurant with your client , just out of respect.

There a different customs and these should be honored ... understanding with the culture your having as a client you should have researched and informed yourself about these customs and conduct yourself accordingly to their customs  

The key to helping cultures understand one another more constructively is first to create the right environment. Merely tolerating is not really enough and sometimes you need to bring co-workers together to discuss their misconceptions and even hang-ups.

With increased experience and communication, co-workers will begin to distinguish among facts, beliefs, values, and personal experience. Sometimes it is merely about being prepared to learn with an open mind.

Furthermore, use an interpreter whenever you give instructions or provide feedback to your employees. There may be someone in your organization who speaks both languages fluently enough to convey your message to your employees, this way you attain the best customer focus competency. 

in this case u need to have a multi- strategy system like so open that can contain various types of customers and u need to have very skilled employees that can handle this task in order to attain the best results of customer focus competency.
