China’s foreign minister cautioned that upcoming negotiations between the United States and Iran will likely be more challenging, as the two nations approach a potential agreement to de-escalate conflict. The assessment came during a phone call with a Pakistani official, acknowledging Pakistan’s role in mediating discussions. This warning precedes the anticipated signing of a memorandum of understanding on Friday intended to end ongoing hostilities. While details of the agreement remain limited, China’s statement suggests significant obstacles remain to a lasting resolution. The Chinese diplomat did not elaborate on the specific difficulties anticipated in the next phase of talks. This development introduces a note of caution as both Washington and Tehran signal a desire to stabilize relations. The outcome of the Friday signing will be closely watched for indications of future progress.
