INTERNATIONAL - Australian winemakers yesterday urged Prime Minister Malcolm Turnbull to visit China to resolve diplomatic tensions blamed for trade obstacles that have raised concerns for an export market expected to top A$1billion (R9.77bn) this year. 

Six Australian wine companies have faced delays at Chinese customs since Turnbull complained of Chinese political interference last year. 

The winemakers held talks with Assistant Minister for Agriculture Anne Ruston yesterday to urge the government to do more to end the trade tensions with Beijing.
