But there have been signs China is seeking to add a number of unrelated measures to the trade talks, and Trump has shown a willingness to entertain them.
Liu arrived in Washington on Tuesday afternoon for economic and trade consultations with the US side at the invitation of the USA government. After the USA unveiled a list of $50 billion in potential tariffs on Chinese products, Beijing responded with plans to implement billions of dollars in reciprocal penalties on US soybeans, cars and other items.
