Guidance is provided on using the clause under the laws of China, Hong Kong, and England and Wales. (For a clause-by-clause guide to the value of boilerplate clauses and the effect of omitting them from business-to-business contracts, see Practice Note, Boilerplate: Do I Really Need This Clause and Why?.)

This clause is adapted from a boilerplate clause designed for use in documents governed by English law, which can be found at Practical Law UK, Standard Clause, Variation.
