Chinese President Xi Jinping has held an unusual meeting with a leader from Taiwan's opposition party, signaling potential diplomatic shifts in cross-strait relations.

Taiwan's opposition party has embarked on a visit to China, a nation that openly threatens the island with invasion, amidst internal political paralysis and a slowdown in Taiwan's rearmament efforts.

Beijing has expressed its willingness to collaborate with Taiwan's opposition party, contingent on their recognition of the "one China" principle and opposition to Taiwan's independence.
